That's fair enough, but also why any larger company should have a broad strategy for marketing and sales as there are a lot of routes that customers take. I once ended up in a multi year contract with a company because I ended up in their IRC channel and I liked it. Did they get most of their customers that way? I imagine not.

That said, DO is pretty well known in developer circles for its thousands of tutorials (less so for its ownership of CSS Tricks which is very recent) but that is certainly not universal.
