Twitter Mac OS X Client
If you use the twitter micro-blogging service and would like to update your twitter status from your Mac desktop then feedalizr, the Adobe® AIR™ desktop application, will allow you to tweet, retweet and share photos on Twitpic from one client.
Twitter Mac Application
There are various Mac OS X twitter applications, widgets and scripts available that utilize the Twitter API enabling you to update your twitter status from your Mac but what sets feedalizr apart from the rest of the twitter mac apps is not the ability to tweet but also to upload and share images to Twitpic and update your twitter and facebook status. Once you or any of the people your are following on twitter's tweets contain a Twitpic URL that twitpic image will be displayed inside your twitter stream within feedalizr.
