For some reason, people often pick one Internet poker site and then just stay there. Don't hang on to one site if it means you can pick up more cash as a bonus elsewhere.

You'll most likely use a third-party holding company as your money transfer agent, so you don't face extra risk to your bank account information by going to multiple sites. (In fact, facing less risk is one argument in favor of employing a third-party holding company.)

Sign-on and special promotions bonuses are a nice inoculation against the potentially debilitating disease of house rake (the money that the site keeps for itself), and you can keep up on who's offering special promotions by signing up for newsletters and updates from every site you haunt.
