Why limit yourself?

[Arjonius]

The more sites you have money one, the more you have to keep track of them. And if those amounts are mostly small, like freeroll winnings, they're not necessarily easy to withdraw. Plus, as already noted in this thread, you'll probably only play on a relatively limited number of sites anyway. So if you play 80 or 90% on say six sites, there may not be much real benefit to having lots more.

I don't see a need to limit or maximize the number of sites that you play at as long as you feel comfortable playing there. I probabloy have an account at a dozen poker rooms, but only play on 4 because of gameplay issues or not feeling secure with a site. At the end of the day, if you are playing the game in a manner of building a bankroll, play solid poker and that will take care of itself.
