I only vote with clear head and vote on all if I am in the challenge!
Comments are tough for me. Sometimes it takes a bit of a buzz to lossen my tounge. I'm never rude to anyone...unless your a bad driver hahaha.
So I vote first then try to comment.
I'm just learning here...so bare with me....I have lots to say but enough for now...
I usually end up voting for all if I have the time. I comment only if I have something distinct, helpful or funny to offer, which is about 15-20%. I can be a bit sarcastic sometimes, but I always try to balance the good with the bad.
