I built it part-time in a week, and then it immediately went to 180 uniques/day. But without (minimal) hands-on involvement traffic has decreased to ~55 uniques/day. The prospect of throwing out all the code and the redoing v2 myself is just psychologically daunting. In looking for a cofounder, I'm mostly seeking social support and motivation (as well as someone a little more technically experienced to complement me)
Respect.
