It seems like the big four are currently (in order of votes):
1 Litecoin
2 Primecoin
3 Digicoin
4 Novacoin

Then there are those deserving of honorable mention (in order of votes):
5 Cosmoscoin
6 YACoin
7 Goldcoin
8 PPCoin
9 Feathercoin
10 Quarkcoin &  Namecoin (tied)

I am surprised by these results so far.  First, I never even heard of Digicoin before this vote and it #3 on the list!  I'll need to look into it.  Also, Primecoin is really close to Litecoin in terms of popularity being a relatively new coin.  It also has a lot of threads for it in this forum (I myself was getting confused and made an aggregate thread for the coin at https://bitcointalk.org/index.php?topic=264115.0

Other new coins that are surprisingly high on the list are Cosmocoin, Goldcoin and Quarkcoin.
