I got used to stackoverflow.com and would expect SemanticOverflow to work similarly. The problem is the website is so new, almost nobody has any reputation that means virtually nobody can vote for your answers, that means no reputation for you and you not able to vote for others and we are in the infinite loop of Catch XXII.
Launching a website with little users and no reputation for them is a bad idea, trying to help users here (nice try, pat, pat) and returning to see if anything has changed (no, it hasn't in a few days - no reputation changes, no real questions or answers) seems to be even less useful (what's the point, if the website doesn't really attract critical mass).
