Instead of stalking Twitter all day, I choice to just follow Mommy Blog Expert. Each week she shares the upcoming Twitter parties, including details on prizes you can win, and links to RSVP! Oh, and make note of whether the Twitter Parties is for the U.S. and/or Canada. I actually attended a Twitter party, won a prize but later was informed it was for Canada only! (I was bummed)
Mommy Blog Expert also gives you sneak previews to parties too.
That way you won't miss out on a great party!
