I'm trying to become more active on stack exchange sites (specifically StackOverflow, but also ServerFault and Meta sites), but I'm having some trouble with it.
I managed to get a small amount of reputation on kiln.stackexchange.com as our company started heavily using the product, but I'm having trouble on the more populated sites like SO, where most of my questions are already asked and questions have answers faster than I can give them.
The problem is, I would like to be able to comment and up- or down-vote comments and answers as a way to contribute to the community, but I can't because I can't find questions to ask or answer.
So how should new users get started on stack exchange sites?
