Going through the setup wizard, you'll be prompted to install a lot of "crapware", make sure to decline the installs. While this is annoying in the install, this prevents ads from being posted in the software during use, which is one thing I can't stand about other IM clients.
Once you get the software installed you can add in all of your accounts. Digsby supports AIM, MSN, Yahoo, Google Talk, ICQ, Jabber and Facebook chat. For email, it can support any POP or IMAP account, as well as Gmail, Yahoo and MSN. Facebook, Twitter, LinkedIn and Myspace are the supported social networking accounts.
The graphical display, as shown below, lists all of your IM accounts and contacts in a top window, with all of the social networks listed at the bottom in tabs. I like the configuration, and this can be edited and resized as needed. There are a few skins available by default, the best of which is the new Windows 7 skin. The chat windows are also customizable with skins, fonts, etc, like other IM clients. By mousing over each of the social networks you can get updates, like status updates on Myspace and Facebook and Tweets from people you follow on Twitter. You can also update your status for all accounts at the same time - a new and great timesaving feature.

Overall, I think it is the best multifunctional client on the market. It's slick interface and great features beat any other client hands down. Check it out!
