“Microblogging” is a way to broadcast small elements of content within a web or social media context. Supporting simple text and link sharing, status updates in Facebook and LinkedIn are at the basic end of the microblogging spectrum. Taking more of a multimedia approach, services such as Tumblr and Posterous add support for longer texts that can also include images, files, music, and video.

Twitter is pure microblogging minimalism, limiting tweets to 140 characters (based on the maximum size of an SMS message). Twitter’s strict interpretation of “micro” has spurred an entire “twitterverse”, 100MM strong. Part of the fun, or some would say challenge, is keeping updates under the limit. Have more to say? Not a problem. Simply blog it – whether through Posterous, WordPress, or any other [micro]blogging platform – and then tweet an intro with a link to the rest. A very common practice. TweetDeck – a microblogging tool that helps to consolidate Twitter, Facebook, and other social media streams – might have you think otherwise.

TweetDeck announced a new “Deck.ly” service that will support tweets longer than the normal 140 limit. Larger texts will be “blogged” on their web site and then automatically intro’d/linked in a shorter Twitter-compatible tweet. Never mind that, with the proper configuration, most current microblogging platforms already handle the auto-crossposting. Claiming credit for solving a problem that had already been solved long ago, this new service was supposedly in great demand by their application’s users.

Excusing TweetDeck for their hyperbole (and their users for their ignorance), Deck.ly does introduce a new player to the microblogosphere. They promise that this is just the start of something bigger – presumably adding multimedia support. No longer just an application, TweetDeck/Deck.ly is now a blog hosting platform. Will Deck.ly remain a closed system only for users of the paid-for apps? Time will tell. But the numerous “Posterous is better/worse than Tumblr” debates may have an additional contender, and Deck.ly will likely require a re-assessment of all the comparisons.
