Eh, what are habbits huh. I'm on many more sites actually. My business site, experiments and joint venture sites. Than business on Twitter and FB - I don't socialize aside from for financial interest. Forums, not sure where to start, a dozen. Blogs... Most of these is work and work related. Networking within my niches and learning stuff.
Today many social websites become a part of our life. Every day i visit on orkut, Facebook, Google, Blogger.com and myweblog....
