For internet marketing professionals..

I shamelessly consider myself as an Internet Marketing professional though I am not doing it professionally. (A paradox?)

What I mean is I don't offer my services to outsiders as I am completely using my knowledge to promote my web sites and blogs.

I frequently visit Sphinn to catch up news on the Internet world, get to know new technologies, visit new websites that are dedicated to web 2.0 etc. "Sphinn is a social site for search and interactive marketers. It's designed to allow you to share and discover news stories, read and take part in discussions, discover events of interest and network with others."-Sphinn

When you share your own post or the ones you find interesting, you can also start a discussion in that post.

An excellent place to network with specialists in internet marketing.
