I discovered Digsby today, via TechCrunch. Digsby lets me connect with all my contacts on MSN, Google Talk and now Facebook chat. Since I have most of my contacts via Facebook chat I really wanted them awailable through an IM client. And now they all are.
after using Digsby for a couple of hours I am even more impressed. All updates from Facebook and Twitter are shown in a non-intrusive way on my desktop, without me having to visit either websites. If I wanted, I could manage my mail also, but this is much more effective through gmail itself.
