I haven't been using stackoverflow for all that long, but long enough to rack up several thousand reputation points.
The last few days, I decided to try and answer a bunch of questions to rack up a few more points. But I've been discouraged at the number of points I've earned.
Yes, perhaps some of my answers aren't entirely brilliant. But in many cases, the OP simply doesn't accept or upvote any answer, or even respond to questions for that matter. In some cases, I identify the problem that no one else identified. But I often go without a single upvote.
I don't recall it being like this before. Is it just me?
