Even after using Google Wave for a few months now, it is still hard to describe exactly what it is. It's as much of a real-time chat room as a platform for editing documents collaboratively. It can also be used as a Wiki, to replace email and IM within an organization, or just to organize a pub crawl, as Wave's Lars Rasmussen points out in today's blog post. There can be no doubt that Wave feels oddly familiar, especially because of its typical Google design, yet it also represents an alien concept for most users, as it combines so many services into one extremely flexible package but still remains deceptively simple to use.

We got a chance to talk to the core Wave team, including Lars and Jens Rasmussen and Stephanie Hannon, last night. They were obviously quite excited about the launch and told us about some of the details regarding the invitation process, Wave's current features, and some of the team's plans for the future.

Highlights

We will look at the details of the launch below, but here are some of the highlights:

• Google will send out more than 100,000 invites tomorrow
• they will go to three groups: current users on the sandbox server, users who signed up for accounts at wave.google.com over the last few months (first-come, first-served), and a few select enterprise users on Google Apps accounts
• more invites will be sent out as the team expands capacity
• users will not be able to invite their friends to Wave directly, but every Wave user will be able to 'nominate' 8 friends who will get to the front of the queue for new accounts
• all Wave accounts will move from the sandbox to the wave.google.com domain
• Wave's contact management system will be integrated with Google Contacts
• the Wave team will highlight robots and widgets from a select number of vendors
• Internet Explorer users will be prompted to install and use Chrome Frame

Wave.Google.com

While the early Wave testers were on a wavesandbox.com account, starting tomorrow, all of these accounts and all the new users will move over to the wave.google.com domain. If you have tested Wave before, don't expect any new features yet. The Wave team plans to add new features over the next few months, but the current focus in on making sure that the system can scale.

Nominate 8 of Your Friends

Unlike the Gmail beta, Google Wave users who get into the preview tomorrow won't be able to invite friends directly. Instead, they will be able to 'nominate' 8 of their friends for accounts. As the Wave team plans to continue to send out additional invites as it stabilizes the system and adds capacity, these nominated accounts will move to the front of the queue and should get accounts relatively quickly.

For tomorrow, Google officially says that it will send out about 100,000 invitations, though as the Wave team told us yesterday, it will probably send out a few more than that.

Google Contacts

Google Wave will be able to tap into your Google contacts (the developer preview didn't offer this feature). For now, it will only show contacts who are already using Google Wave, though.

Invite a Robot to Your Wave

On Wednesday, 100,000 users will also be able to use some of the robots and widgets that the developers in the preview wrote over the last few months. These range from widgets that allow you to play games with friends to sophisticated teleconferencing apps, with Twitter and blogging apps in between. We will have a close look at some of the more interesting applications tomorrow, but the featured apps will include a real-time, competitive Sudoku game, a Lonely Planet travel widget, and video chat from 6Rounds and a teleconferencing plugin from Ribbit.

For now, Google Wave will not feature an app store or marketplace for widgets and robots. Instead, every user will see a wave with a small number of featured apps in their accounts and be able to install these thanks to the new installer process the Wave team introduced just a short while ago.

Chrome Frame

When Google launched Chrome Frame, it's Internet Explorer plugin that can replace the IE rendering engine with Google Chrome, the Wave team already announced that it would support this feature. And indeed, when you go to the Wave homepage with IE, you will now be prompted to install Chrome Frame. As Lars Rasmussen told us, the team is very enthusiastic about Chrome Frame, as it allows the developers to focus on features instead of making sure that Wave runs in Internet Explorer.

In our own experience, Wave definitely works best in Chrome. It will work just fine in Safari and Firefox, though for the most fluid experience, Chrome is currently the best browser.

Still Some Kinks to Work Out

The Wave team stresses that there are still a lot of problems to work out before Wave can really live up to all of its promises. While there was some doubt that the Wave team could actually get the system scaled up and ready for a wider launch earlier this summer, our experience with the developer preview has been very positive over the last few weeks and we definitely noticed that the system became fast and more stable. Now that 100,000 new users will join in, we will obviously have to wait and see how well Wave can scale up to this kind of demand.

For now, chances are that Wave will still crash at times. For major updates, the team will also have to take the whole system down for a few hours now and then.

Missing Features

Some features, however, still need to be implemented. Some of these are quite basic, like the ability to remove users from a wave, while others are a bit more complicated, like the ability to set specific user permissions on a wave. According to the Wave team, many of these missing features will be implemented within the next few months.

How Will People React?

Overall, it will be interesting to see how the Wave infrastructure holds up tomorrow and how people will react when they first see and use Wave.

So why give it a second look? One reason: attention to detail. Most noticeable is an obvious concern for the aesthetic of the product. You get the idea that look and feel are important to the company when you first land at the Survs site - and that thoughtful design continues throughout the product from the survey composition tool to the reporting features.

But that's not the only detail to which Survs pays attention. The site leverages AJAX to make the survey creation process easier on the builder. No more saving and refreshing to see changes. Just double click and type. Survs saves everything on the fly. A small - and seemingly insignificant - touch that vastly improves the speed with which one can compose a survey.

Another example of "attention to detail" can be found in the look and feel of the surveys themselves. Themes and templates allow users to customize the colors of the simple and well-designed surveys, as expected. But what was unexpected was the option to edit the language of the survey down to the "Next" buttons.

Finally, Survs offers the option to run surveys through multiple channels at the same time. For example, you could send a survey out by email, embed it in a page, and link to it from somewhere else. Each channel can be monitored separately to determine the most effective means of interactive with your audience.

Now, the downside. Survs is currently in private beta for a reason. It's fragile. The server tended to choke while we were performing some basic functions. And survey embeds failed on a couple of occasions. But some of that fragility may stem from the fact that we're accessing Survs from the United States. (It will be interesting to hear if our European readers experience similar issues in reaching this Portuguese company.)

Suffice it to say, we wouldn't recommend using it for "mission critical" surveys at this point.

If you're already in love with a survey tool, Survs may not dissuade you from using it. But if you're new to the world of online surveys or have never really settled on a solution, Survs could be exactly what you're seeking.

Survs is currently in private beta. But, they have given ReadWriteWeb readers an access code to register for the service. Simply visit the registration page and enter the code F6W6HGOD. The offer is limited to the first 500 people, first come, first served.
