"Yeah, I think LW genuinely does a pretty good job of balancing the tightrope between hardcore 16-hour-a-day grinders and "log in for 5 minutes for dailies once a day" players."

The pebbles you get for not excessively grinding though generally can't be used to buy much for you on the site though, at least not right now. KS backers also get help from the big pebble rewards their companions give them, but not everyone bought into the KS.
