I see an upvote arrow next to comments and stories, and I'm a very infrequent poster with next to zero karma.

No idea how to tell if my upvotes 'count' or not.

I have <500 karma and can upvote. Unless it's not actually doing anything.

I have other friends that have low Karma points and can upvote. Its definitely not a Karma threshold.

That threshold is for downvoting. Upvoting - at least for me - has been available since I created my account 3-4 months ago.

Oh, of course.
