Everyone one has a favorite program. It can be a desktop app, web service or mobile app. It's the one application we constantly turn to through out our day. My favorites are ones that mashup other services with new tools.
Here's my favs:
The Social Web Browser. Flock integrates well with Facebook, Twitter, LinkedIn, You Tube, Picassa and web mail. It has a built in RSS reader, media stream viewer and blogging tools. Flock is built using the Firefox framework, so any FF extensions will work in Flock. Read more in my blog.
Xobni (inbox spelled backwards) is a must have for any Outlook user. Besides lightening fast searches, xobni pulls info from LinkedIn and Facebook to Contact info, profile pictures, company info, job titles. All organized. Automatically.
