- What is Stack Overflow's business model? 7 answers
I remember hearing (can't find a link right now) that advertisements aren't shown on most sites - in fact, in my simple study, they were only shown on the Trilogy.
What is the motivation to launch more sites? All of SE's revenue seems to come from ads and Careers - which is targeted at programmers. Not gardeners.
It's awesome, of course, that there is a site for almost everything. But what's in it for SE? If you aren't showing ads, and your users probably won't use Careers, you're not making any money. So what's the plan for monetization? Is the idea just to expand web presence/reputation?
Of course, I don't expect an answer. Future plans are probably locked down tight. It just occurred to me, and I thought to post this out there. SE is awesome.
