"Demand" is the answer. Or to be more precise, the lack of it. We can have 1000 sub-forums here if we want to dedicate a place for every topic that gets consistently talked about (like Digg, StumbleUpon, MySpace, Social Marketing, Muslims, NFL, YouTube, MErgers and Acquisitions, PR Updates, Infractions etc. etc.). But that would not make this a better forum. To break it down for you: E-Commerce's general business issues like shipping etc. can go in the Business Forum. E-Commerce's shopping cart talk goes into Programming. E-Commerce's marketing stuff can go into Marketing. E-Commerce's SEO is the same as any other SEO so it can go in SEO. So really, we already cater for every aspect of e-commerce. And if one day we find E-Commerce talk taking over a certain forum, we won't hesitate to dedicate a section to it.
