Usability 
Mobile portal and social network Fonet now features Google Buzz integration. Fonet users can view their Buzz timeline and post Buzzes without leaving Fonet.This is the first third party mobile web based Buzz client I've seen.
Buzz is just the latest in a long list of online services and social networks, including Facebook, Twitter, Linkedin, Friendfeed, Flickr, YouTube, Picasa, Google Calendar and Docs, Delicious.com and Tripit that Fonet integrates with.
Fonet also includes:
A customizable mobile portal with mobile web directory and the ability to add your own links and RSS feeds.
The Fonet social network with profile pages, friends list, messaging, groups and blogs
A personal information manager (PIM) with online phonebook, to do list, contact manager and cloud storage.
