I'm new to Stack Overflow and haven't any reputation points. I just got my first question answered, and I tried to upvote the answer, but I get a popup that says I don't have enough reputation points yet.
I can understand the basic principle - give people incentives to "give back" to the community, so I don't have a problem with restricted privileges at first.
But it's my question! Who's in a better position to judge if it's a good answer or not?
(Note: One of the answers to the Meta Stack Overflow question Why don’t people upvote questions they answer implies I should have been able to upvote in this instance, but I can't. Change in policy? Bug in the code?)
