I totally understand why the karma is kept hidden, to avoid herding votes, but I also really miss the access to the HN community barometer. I placed great value in the information contained in those vote tallies, and it hurts to have that taken away completely.
A compromise would be for voting to be disabled on all threads after x days, with vote tallies being displayed at that point.
If you guys want to fancy it up, you could have a button at the bottom of the page that says, "OK, I'm done voting now, please show me the tallies", and the voting buttons would disappear, and tallies would appear in their place; and you'd only have to keep track of x days worth of user thread status flags before you can purge the data.
Also, the vote tally could be displayed for a post once you've voted on it.
