I hate to be _that_ guy, but for someone who values the opinion of others as you apparently, do, using 'whom' on the internet isn't likely to win you over any friends. Let alone using it incorrectly...
1. proselytism 2. grammatical solecism 3. inflating the value of a "downvote"
In hindsight, I should have kept my mouth shut. But hit those three before my caffeine deficiency has been addressed, and I'll likely find myself in _that_ role.
Is there any other kind? I will admit the whom-bomb was unpleasant.
OP: If the answer is not him/her the question is probably not "whom."
