Have a great web idea, which is somehow similar in terms of requirements to yahoo answers. How much it may cost me to build a site (just web, ignoring marketing) similar to yahoo answers? Thanks.

You may find that it could cost from $200 to $5,000. The way to find out for sure is:

1. Write out your requirements and try to outline everything so that someone could build the site from your descriptions.
2. Post a job request on RentACoder, Elance, or Guru.com

You'll get bids and people will tell you exactly what it can be done for.
