The problem about cash game on SWC is, and will always be, traffic. The campaign in here didn't change anything about the biggest problem of the site, there are just NO PLAYERS at all.
Just checked right now and it's the usual under 150 people online, and it's always around that number, no matter if weekend or whatever. There are exactly 7 cash game tables running right now, one of them is super micro stakes where you play for cents. I mean, come on, with these small numbers of players what can you do? Wait forever at a table to get joined? That's why most of the tournaments aren't running as well, the min amount of registrations often don't get met.
