Initial thoughts:<p>Way too much stuff going on. Why are you forcing my scroll to be messed with? Most sites that have *ninja in the name I immediately think of as immature. On /browse/ you have just WAY too much javascript happening. I'm tethering on a 3G connection on a train right now and it took > 30 seconds to load everything.
I like the idea a lot. I worked at a larger company who offered a consumer service like this for a while. We found that most consumers really didn't convert well for the service and we had to pump in lots of marketing to get results. The most popular categories were 'psychics' and 'health'. Basically people who had STDs and were embarrassed and people who wanted their fortunes told. That said, there was a non-trivial amount of cash in those topics...<p>edit- I forgot programming. That was a big category as students often wanted their homework done for them...
Feedback: The image gallery type of thing on the search ninjas was neurotic on my machine and I'm running latest Chrome and Ubuntu. By neurotic, I mean that it jumped around quite a bit. Not smooth at all.<p>Take out "ninja." Yoga ninja? Golf ninja!? I just want a Golf Instructor...<p>Btw, what company are you going through to get the video chat? Did you do that yourself?
Congrats on launching. The site looks great.<p>Some feedback:<p>* On the browse page, you should remove the ninja after the person's expertise. It makes it easier for the expertise to stand out when scanning the experts.<p>* It wasn't immediately obvious to me that the green circle meant that the ninja was available now--maybe something more obvious if you want people to start a session in an ad hoc fashion vs scheduling a future session.<p>* It might be useful to show the people an onboarding page with the type of help you could get from these ninjas.
The "Browse Ninjas" page has some extremely distorted photos. I am not sure if your tiling is algorithmic or what but it's probably not very appealing from the perspective of the people on that page (or the people seeking them out).<p>(edit: Firefox 15. Have not tested in Chrome)
Congrats on launching! I love the idea - this is somewhat similar to clarity.fm.<p>The site itself is pretty but seems to have some UI issues which are slowing down the site.
