First off I check my email, then:
Washington Post
MacRumors
Nikon Cafe
DPreview
Inevitably through perusing info or posts on one of the above, I find myself hopping to Google to look something up or to B&H to see a specific description and price of a lens (I've found that is a quick way to learn about specifics even if I don't intend to order anything there).
If I have time and motivation I check my GMail accounts where I have my Yahoogroups subscriptions and catch up with those...
By the time I've done that it's back to checking my email again, and then another look at the Post, another stop at MacRumors....you get the idea!
