After a busy couple of days, oneforty app store founder Laura Fitton is in the unique position as the unofficial spokesperson for a developer community turned upside down in the wake of the Tweetie acquisition and Promoted Tweets launch. As the company hosts its first Chirp developer conference, thousands of coders are questioning their role and ability to monetize on the microblogging platform. Always an optimist, Fitton and oneforty are intent on collecting and answering the many questions plaguing developers.

Xtify's recently launched geo-messaging platform is demonstrated in a new YouTube video created by Motorola, makers of popular Android devices like the Motorola Droid smartphone. The Xtify geo-location platform and its associated SDK (software development kit) was announced at February's Mobile World Congress in Barcelona. With the SDK, developers can integrate geo-targeted messaging into their applications, starting with Google's Android mobile operating system and later arriving to the Blackberry, Symbian, Windows Mobile and iPhone operating systems.

Prepare for your mobile apps to get a lot more pushy.

At today's Unite Conference, game dev platform provider Unity Technologies announced it will be releasing the latest build of its Unity Platform and making a previous version available at the low, low price of free.

All platforms allow developers to create games for PCs, Macs, Nintendo Wiis, and iPhones. The free version, formerly known as Unity Indie, was previously priced at $199. Broke and/or stingy devs are welcomed to download the platform here. The pro version of Unity's platform will continue to sell for around $1,500.

Israeli startup and instructional video platform 5min is on a roll. Since moving to the US, the company has raised $7.5 million in Series B funding from Spark and Globespan Capital Partners, and it's just signed a content and advertising partnership with major lifestyle TV network Scripps. Scripps programming such as content from HGTV, The Food Network and the DIY Network will be syndicated through the 5min site. Meanwhile 5min will also share some if its content back to the Scripps online properties.

While it's unlikely that Twitter CEO Evan Williams was wearing a Dr. Evil costume when he delivered the news, he had the pleasure of announcing his company's $1 billion dollar valuation today at an all hands meeting. According to TechCrunch, the company has raised a $50 million dollar funding round and the money will be in the bank shortly. Given the fact that Twitter turned down an offer to be purchased by Facebook earlier in the year, it appears the two are about to tango.

When the President of the United States warns schoolchildren to watch what they say and do on Facebook, you know that we've got a problem...and it's not one limited to the U.S.'s borders, either. People everywhere are mindlessly over-sharing on the world's largest social network, without a second thought as to who's reading their posts or what effect it could have on them further down the road. For example, did you know that 30% of today's employers are using Facebook to vet potential employees prior to hiring? In today's tough economy, the question of whether to post those embarrassing party pics could now cost you a paycheck in addition to a reputation. (Keep that in mind when tagging your friends' photos, too, won't you?)

But what can be done? It's not like you can just quit Facebook, right? No - and you don't have to either. You just need to take a few precautions.

Amid the hubbub over new iPods and iTunes' LPs announced at last week's annual Apple event, one feature that was a little under-hyped was the new "anti-phishing" protection built into the iPhone's Safari web browser. The added feature, available via an iPhone software update, warns users when visiting fraudulent websites using Safari. This sort of technology is already commonplace on the web, but is rarely seen on the mobile platform.

Unfortunately, there seemed to be a problem with the new security feature: it wasn't working...or at least, so it seemed. As it turns out, the problem was that users weren't informed as to how to properly activate the anti-phishing protection, an issue that points to a poor implementation of what could and should have been a major breakthrough in mobile computing technology.

Facebook used Nokia World, the mobile conference taking place now in Stuttgart Germany, to make a major announcement about the expansion of their Facebook Connect platform. According to Henri Moissinac, head of Facebook's mobile operations, the company is launching a new program called "Facebook Connect For Mobile Web." The Connect platform, which originally launched in 2008, is already available for traditional websites as well as Apple's iPhone. With this update, it can now exist for any mobile platform, too.

Are any application developers making money on Facebook? Not really, but they could be. According to Bruce Richardson of AMR Research, less than 2% of Facebook developers make any "real" money. Part of the problem is that Facebook has not had any decent e-commerce engine for monetizing applications - until now, that is. Instead, developers have had to rely on the advertising model, which isn't always a good fit for their type of application, nor is it all that effective. Z-Commerce, a new service launching today at DEMO 09, aims to address this problem. But the big question is this: are there any Facebook applications worth paying for?

Much has been written lately about the rise of the API. Offering a programming interface to an online service is now standard practice amongst this generation of web companies. Through APIs, we get to enjoy a range of innovative Twitter clients, wide availability of maps and location information, custom search engines, and more. However, delivering superior user experience on major platforms should be as much of a priority as opening up via an API.
