In my previous post I wrote about ping.fm and their service to send notifications out to many social and business network/apps.
A different approach is used by the Adobe Air based app called Feedalizr. It lets you share your texts, photos, videos, etc. as well, but also allows to read and interact with posts from friends. All of this on your local desktop, no web browser required (although you need to have Adobe Air installed on yout computer.)
This is a very interesting approach and they try to be your central application to post AND read (and interact), resulting in less application switching between your different websites and services. They currently support Twitter, FriendFeed, Flickr and Jaiku.
The software just came out off public alpha and is now available as a beta version. Go, check it out and respond in the comments if you use the app or know of other cool apps helping you with keeping up with your social network buzz.
