Alert Thingy, the FriendFeed desktop application that launched just three days ago, just launched v 1.2 of the service, with Twitter support.
In addition to viewing FriendFeed data streams and posting directly to FriendFeed, users can now also post directly to their Twitter account as well. Users cannot directly view Twitter streams through AlertThingy, although they can get that information by following FriendFeed users who include Twitter data.
This makes FriendFeed even more useful. Twhirl, a competitor that was recently acquired by Seesmic, works with Twitter, Pownce and Jaiku, but users rarely use more than one of those services. Lots of people use both FriendFeed and Twitter, however (FriendFeed often to read information, Twitter to post), and they may find Alert Thingy a nice alternative to Twhirl.
I’m finding that I use FriendFeed a lot more now than I have Alert Thingy installed. And if they continue to innovate this quickly, I may find I uninstall Twhirl for good. Things they need to add – the ability to view Twitter directly, outside of friendfeed (including replies and direct messages), and integration with snurl to easily shorten included URLs.
