Enter HelloTxt, a client for all your microblogging platforms. It supports all the sites listed above, plus Pownce, Bebo, Jaiku, hi5, Plaxo, Tumblr and a bunch more I’ve never even heard of. And it’s free!
The user interface is incredibly simple. Your dashboard is a posting form with your default services checked (you can uncheck them if you don’t want to post a given message to a particular service). It also shows your recent posting history:
Another screen lets you input your account information for the various services and determine which ones are checked by default when you post:
There’s also a timeline screen which serves as a client for some of the services. It doesn’t support LinkedIn yet, though, Facebook is “coming soon” and with it being a static HTML page, it’s not a very functional Twitter client (I use Twhirl myself).
This is yet another small piece of the “social networking client” we envision in The Emergence of The Relationship Economy. Combine this with FriendFeed, Quotably (but across multiple platforms), a profile aggregator and an Ajax-based personalized home page, and now you’re talking about something really compelling. I just want them all in one neatly integrated service.
In the meantime, HelloTxt is a new essential in my toolkit.
