What if Twitter understood what you were saying and could then take action on your messages? What if Twitter wasn't just a place to post your random thoughts, but an A.I. bot that actually helped you get your work done? That's the concept behind Akibot, a new enterprise microblogging service. At first glance, Akibot may look very much like your typical Twitter clone, but it does something very different: it combines the collective intelligence provided by microblogging with an artificial intelligence engine that lets the service take action on the messages posted.

Everyone's Robert Scoble's favorite real-time microblogging service, FriendFeed, is now allowing users to post and download many kinds of files through their site.

Sadly, video files are not on the list of accepted formats. Yet. And users can only upload three MP3s in a 24-hour period. However, other file types, from PSDs to RTFs, are accepted and up- and downloadable.

ThisMoment is a new media-sharing site (see our previous coverage) which lets you post photos and videos in a slideshow format while also sharing them across the web to sites like Facebook and Twitter. Part microblog, part social network, and part sharing platform, thisMoment's goal goes beyond simply providing a place to store and share your media. In other words, it's not just a Twitter clone with pictures. Instead, this beautifully crafted site is designed to allow you to share media that has meaning to you - the special moments that will in turn create a "digital reflection" of your life.

Central Desktop, a leading SaaS collaboration platform, has entered the ranks of those adding microblogging capabilities. The announcement comes as part of the first day of Enterprise 2.0 conference.

Twitter-like short messaging is the hot new supplement to the feature set of collaborative tools, and there are more than a few startups that revolve around standalone microblogging. But rather than a new interface within the platform or a separate app, the new addition is seamlessly integrated in to Central Desktop's preexisting activity stream.

Socialcast, the enterprise communication and collaboration platform oft-compared to Friendfeed, is making its basic service completely free, with no limit on users and administration capabilities.

This news marks a tidal shift in strategy for the company, since previously only a 10-user version was free, and was $1 per user per month after that. As of today, however, Socialcast will divest itself of subscriptions altogether, making a clean break with the model that competitors Present.ly and Yammer have long used.

Enterprise microblogging app Present.ly has added two new features. The first, announced on the 12th, is the ability to import external RSS feeds directly in to your stream. The second, revealed today, is a bevy of new metrics and statistics on claimed Present.ly accounts.

While neither is exactly groundbreaking in microblogging, their addition is a boon to users. They're also a sign that the company can keep pace among a throng of swiftly-moving competitors - such as Yammer and Socialcast - that have already added similar functionality.

Microblogging has become a very popular way for people to share news and information or even live-blog events in real time, but if you have ever tried to search through services like Twitter using only Google, the Twitter native search or any number of other services, you know how difficult it can be to find exactly what you're after. Today the Google Operating System blog reports that Google will be launching a new microblogging search service that will sort results by relevance and integrate those results with its own web search engine to trigger a "microblog universal search group", closely related to the way Google Blog Search works. If it turns out to be true, this is great news to those of us who constantly search Twitter for the latest news and trends.

Launched earlier this month, Obayoo (pronounced oh-bio) is a private social network for microblogging and file sharing within your company. It's available for free on a SaaS basis and accessed through your company email address.

Obayoo appends a Twitter-like interface with the kind of features that Twitter itself has yet to implement, such as threaded replies, groups and file sharing (including images). Along with enterprise microblogging tools like Yammer and Socialcast, Obayoo also has the ability to draw in numerous RSS feeds, including selected Twitter accounts and searches.

A few weeks ago, we heard that Yahoo was readying a Portuguese-only Twitter clone under the name Yahoo Meme. Today, we finally got our invitation to try this new service, and while it is indeed an interesting micro-blogging service, we wouldn't go as far as calling it a "Twitter killer." Instead of cloning Twitter's communications features like @ replies and direct messages, Meme goes back to the basics of micro-blogging. Users can upload photos and post text (without a 140 character limit), YouTube videos (just copy and paste the URL), and links to MP3 files.
