Even if Paradise and Party were to "reopen", would they be the same, or merely a shell of their former selves? Would players go back, or would they stay at whatever new sites they had settled at? Interesting question....
I have a love/hate relationship with Partypoker. Every once in a while they do something retarded (like introduce the Mon$ster or ban US players) and I denounce them and angrily switch sites to UB or FT or Ongame or whatever.
It always ends the same way. I crawl back. They got the only software I'm really comfortable with, my winrate and hands/day are nowhere near the same level on any other site.
