For users who see SO as a "one-way street" would it be appropriate to post something like,
May I ask, with 53 questions and 0 answers, why not show a little more appreciation to those who have helped you (12 votes cast over 10 months)? StackOverflow is about community help, and need not be a "one-way street".
I ask because after posting a good answer to user Solingis I see his stats and now think that since this person doesn't seem to be a part of the community, I feel like I have been his tool not helper. Certainly this user is not the only one of the sort and I have wondered this before. Thoughts?
