Snitter is a twitter client built on the Adobe Apollo platform, that means it is a full cross platform application. It has several tabs to get info on yours and your friends and followers tweets.

Features

• highlights messages sent to you via @ syntax (and makes a chirp)
• clear current list of tweets
• refresh list of tweets
• displays last time it tried to request an update (so you know if it crashed for some reason)
• view 20 most recent items in your timeline
• view 20 most recent replies
• view up to 100 friends (most recently updated) and filter by name and screen name
• view and filter followers
• links to easily @reply and Direct message users

We stumbled across this Twitter Client today that runs on Adobe Apollo runtime platform. It looks like it is worth a look, it has URL shortening built in too. It runs on both Mac and PC. We haven't used it yet so let others know what you think if you try it. .

P.S. - We have a list of about 20 apps that are waiting to be added into the Twitter Forge. They will be posted over the next week here...

"Apollo is the code name for a cross-operating system runtime being developed by Adobe that allows developers to leverage their existing web development skills (Flash, Flex, HTML, JavaScript, Ajax) to build and deploy rich Internet applications (RIAs) to the desktop."

Here is the first Twitter + Apollo application. We haven't tried it but will let you know soon how it works out.
