  2. Lycos eh.. that’s oldschool.. Thanks, I’m glad you enjoy. At the moment I am still scattered all over the web. I am implementing at the moment as twitter knock-off, same with as an asocial networking something… I post on and here most at the moment though. The RSS feeds here work and am working on tying everything together.. Are you a web dev?
