That and finding a question you've search for, only to find out that question was also posted by you years ago. Bonus for ones with no answers still.
Now you hit the same problem search -- and find you original question. But wait! Now there are half-a-dozen other people with the same problem! So you click on all of those links.
But none of them could find an answer either. Bonus points if there's a guy who comes in condescendingly and quotes a manual or some other standard piece of information -- which is also wrong. This is usually because they didn't pay enough attention to understand the question in the first place.
It took two hours to carefully craft my question just to have it immediately shot down. It is needless to say I have not posted again since.
I just assume that my question won't fit their guidelines, regardless of what it is, these days.
I think they're over-moderating the site. It's a shame because it's MUCH better than what was before.
I'd say at least half of the questions/answers I come across are closed flagged as vague, or whatever but at the same time, were incredibly informative, useful and exactly what I was looking for.
The SO moderators need to chillax a bit.
I always answer my own questions if no answer was given and I found a workaround/hack to solve it. Not for myself, but chances are that in few years, if I search for the same question I'll find my own.
P.S. Recursive bonus: closed with a comment ("you should just google it") and now actually the top result in search output (happens quite frequently) :)
To comment on the headline, I am an experienced developer who also uses Google and DuckDuckGo several times per day. It's often faster to look up a method in the Java or Ruby stdlib that way, rather than navigating through the official docs hierarchy.
