I thought it was "common knowledge" that there's a 500 karma threshold to upvote? However, I couldn't find anything "official" right now, other than a reference under:

(I thought it was in the faq? Did I miss it?)
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.
Given that most people in this thread complaining about their upvotes not registering seem to have a karma below 500 it might well be that. If that's the case I'm surprised they didn't make it explicit by removing the arrow altogether (like the down arrow is not displayed when you don't have enough karma for it). Seems a bit deceitful.
That being said it might just be a bug somewhere.
There's a karma threshold for downvoting and flagging. Those are not new but I ventured a guess that there may now be a similar threshold for upvoting.
