Just judging by a few friends that played online poker in the last two years, most have greatly reduced their playing time (including myself) and some have stopped. It's very time consuming and for some expensive. The number of the sign-up incentives have dropped significantly and even
Party Poker made their Reload Bonuses more difficult to collect. I think the market is saturated and the "Side Games" are ripping off the players IMO. They are a quick profit for the site, but they lose players in the long run.
