Sorry about my original reply on this one, mate. It sucked.
The cap is 240 votes. I almost hit the cap just upvoting most of the comments here yesterday. If I participated in any real discussions outside of my own comms, I would almost certainly hit the daily cap on that given day.
Damn, I certainly can't imagine voting 240x in a single day. There might remotely be that number of opportunities in my subscribed stream, but that would be like me forming an opinion upon every-goldurn thing that I possibly saw in that day. And beyond, really?
I mean, sure I suspect I'm like you and others, giving a friendly updoot upon loads of stuff that I was only neutral upon, but it was for the 'good' of the FV, but... 240x per day, y'all?
