That's interesting, I teand to get to SO as a result of a Google search rather than searching directly.
Also I find most questions are simple implementation issues or bugs, rather than around complex design problems. Perhaps I am missing a trick...

Likewise. I started noticing that SO results to software-related queries were of sufficiently better quality that I started to qualify some searches with site:stackoverflow.com. (Similarly, I also add site:ycombinator.com with some other types of searches.)
It's too bad that SO/SX has fragmented their URL structure to make the site: qualifier less effective. E.g., it would have been better to have developer.stackexchange.com, superuser.stackexchange.com, etc. Then you could choose to do just site:stackexchange.com to search the whole corpus vs site:developer.stackexchange.com to be more narrow.
As far as actually asking questions, I've been on SO for a few years so I've used it for a lot of different things over time. I used it when I was first getting acclimated with C and Java outside of class projects, and now I use it whenever I'm picking up a new pet language. I've been asking and searching a lot about Haskell lately.
