I don't see why self-funding should be surprising at all. It's very cheap to start an online start-up nowadays.
I think the whole "make something people want" motto can be profitably expanded to "make something people want enough to pay for it".
I strongly suggest you watch DHH's talk at startup school. http://www.omnisio.com/startupschool08/david-heinemeier-hans...
How easy is it to become a member? I am working with 2 other people to build a site during weekends. I don;t really have a bio online and it will take me a while to build up a suitable LinkedIn profile. Do you think this might be a problem?
We are starting a new company, www.nixty.com, that is more Web 2.0 and less of a tried and true business model. We can do it because we have revenue from our first company. I probably would have sought Angel funding if we didn't have some extra money to invest.
