- The idea is great, and something I think a lot of people would find useful.
- The UI in general needs a lot of work. I'll point out a few things that could be quick fixes, but I think you'd really really benefit from paying a good UI designer to rework it.
- The "City" dropdown on registration was confusing for me since I don't live in any of the cities listed and almost didn't see the "Select another city" option. Might be better off with a text field and possibly autocomplete.
- Even though I said I'm looking for a mentor on registration, on the next page, none of the "Looking For" checkboxes were checked. I get that that was probably intended since that's a search, but it still confused me.
- You might want to change the Thank You For Registration message to Thank You For Registering.
- This is what my Location dropdown looks like: http://i.imgur.com/CjHqb.png even though I don't live in California...not sure why that's on the list.
- The "Please Complete Your Profile" box in the sidebar doesn't look like a link even though it is.
- IMO it could do without the Microblog/Following sections...people are still going to use Twitter for that, and I think it just adds confusion to the backend to see that included. The other alternative is just to have it integrate with Twitter, so that if you follow someone, you're really following their twitter user and yafounder is just providing an alternative interface, but even that is IMO unnecessary.
- It could really benefit from some sort of tour/wizard to help navigate the backend. There are a lot of links and it's not immediately apparent what most of them do.
Great idea! Hope it takes off for you.
