This poll didn't have the right question that applies to me. 

I vote and sometimes comment.

Like all threads, I can read the title (if carefully written) and tell if it applies to me or is something I would be interested in reading/commenting on, so I don't participate in all polls I see.  To me, a poll is just a head-count added to any other thread.  All threads are about different opinions of whatever is at issue.  Sometimes, we think we know how others will answer so we compartmentalize the answers and let the other users select from our predetermined list.  I like open ended threads myself because I can't know all the possible answers when I start a thread.
