Okay, maybe not "by yourself" but what's the point of hanging at a poker site with 12 other players? I've been to several online poker sites and I see just a handful of people... not even enough to field regular tables with more than 3 or 4 people. It would be soooo much better if people would consolidate to fewer poker sites. There just isn't the player base right now to play so many poker sites.
This is a good question. I've played at the busier sites - SWC, Betcoin - and also several of the smaller sites. A couple years back I had a positive experience at Satoshi Poker ... back when it was basically just SWC and tiny SP. What I liked about playing SP, and now some of the smaller sites, is that the mix of players is different. For example at the bigger sites at any given full-ring table I'm competing against several players that I have no history on. I don't use hand analysis software, and I don't multi-table like some autistic automaton - I like to play real poker against a real person. (Yeah, online game is not for me, that for another time.) So, often at the bigger sites I just feel at a disadvantage. Its not my best game. At the smaller sites I'm able to level the playing field a bit because the players showing up at these sites are less dedicated to the online grind. Moreover given that I don't use software to keep track of hand histories it is easier for me to internalize a history on the much smaller field of opponents.
So for example at Luckyflops right now I know that Jorjitofish and Fishkiller can always be found at the cash tables, and I've now played them enough that I can sit down and 'play the man' as opposed to playing some multi-tabling or multi-accounting bot. Actually at LF there are roughly about two dozen characters that show up somewhat regularly. I am a home-game cash player and when I play online I appreciate seeing familiar 'faces' at the table.
A second reason is that the newer sites tend to run more aggressive promotions (?), and often the promotions are run inconsistently, so that allows me to 'corner the market' from time to time. Anyway, there are pros and cons to playing both large, well-trafficked sites, and the smaller start-ups. I think both have their advantages and disadvantages.
