Three-way merge: Seesmic, Twhirl, and Ping.fm getting together | Webware – CNET
Also coming to Twhirl in the upcoming release is support for Ping.fm: You’ll be able to use the client as a front-end to your Ping.fm account, which means if you like the Ping.fm service (like I do) for its capability to multi-post items to several services at once, and also like the Twhirl service for reading your microblog feeds, soon you’ll be able to take advantage of the Ping.fm functionality without actually leaving the Twhirl client.
I may have to go back to Twhirl if they are going to add support for Ping.fm. Although now giving TweetDeck a try and liking groups.
