I tried Titan 7-8 months ago and I can say that the micros on Titan (and ipoker in general) are bot/nit infested and I believe that the situation hasn't changed dramatically. So, if you like playing pots for 15-20c (because this is the average pot size at 4 nl I think), then go ahead, have fun stealing blinds from bots/nits every once in a while. But beware, they can fight back!
