I've been lurking Stack Overflow whenever I had a problem for at least the last 2+ years. More times than not, I find my solution (or cobble one together) before I get frustrated enough to have the innernets help me with my specific custom problem. Many times, the only commentary I would be able to add would be "thanks!" which really only wastes bits and bandwidth.
I understand implementing measures to keep the bots and SEO kids out, but sometimes it's a PITA to start participating in a community.
If you couldn't extract my question from the above rant (or title), this might be a little more clear:
Why do I require 15 reps to just up-vote something?
I feel like it's kinda silly.
Additionally, I noticed the quote off to the left:
We prefer questions that can be answered, not just discussed.
yet I have looked around here and haven't been able to find any justifiable explanation.
