would be nice if there was some way to encourage playing currently... the tables are pretty dry. i know other sites are doing freerolls for players that play x number of hands on that day. maybe something if you earn x amount of krill you qualify for a nightly/weekly tourney.
Have you tried table starting? I think a lot of the problem is that everyone has the same point of view...they log in, don't see a table running of what they want to play, and either leave or sit in the lobby waiting for someone else to table start. If you open a table and request action in the lobby, you'll def get some takers.
