OpenTopic

[take5]

Been noticing OpenTopic a lot these days. it's on military.com and financial times. i did a search on google for opentopic and found some more. how many sites use opentopic and how many sites use vb?

AFAIK, those numbers aren't public information...

You should, however, base your decision not on popularity, but on the quality of the product and how it fits your needs.
