I looked at that password list. Only around 1800 passwords were kept in regular md5, those are piss easy to crack (see http://www.md5decrypter.co.uk/ if you don't have a rainbow table setup already).  Otherwise you are fairly safe, provided your account is not one of those with regular md5 hashes (the ones not starting with $1$whatever are regular md5s).

lol, that is so I wrong.

I iz leet hax0r thanks to random interweb link!

Not bad, but what about those mining ops who have hundreds of cards? What if THEY turn to cracking? 
Hail the emperor above!!!

I actually thought about this.  I took the top miners from various pools and compared their GHash rates to my own and figured that it scales linearly (it probably gets a better coefficient than I was giving it but I doubt it changes the order of the function).  Which puts the estimate at ~ 4 years.  That's assuming they are cracking my hash and only my hash (obvious the time increases by n for n hashes) .  To worry about my password being cracked in one month (i.e. P=.02/day) I'd either have to get the attention of 48 of these folk who own >$10K worth of GPUs or postulate that there's some mysterious person who has half-a-million worth of modern GPU equipment. (and all other permutations therein).  Probabilistically speaking I'd say I'm in the clear.......unless someone sics 天河 on me.
