If you're happy, and you're doing well, getting paid decent, like your coworkers, and are still learning, there's not a whole lot of reason to move, I would say. The grass isn't always greener.

If you feel like you've gotten in a rut or plateaued, that might be a reason to think about it. I suppose it depends on your local job market; some places expect a lot more churn than others.

Personally, I'm kind of adverse to change for change's sake; I'm going on six years with the same company, and, except on my worst days, not really thinking about moving.
