Rachel Harrie's fourth writer's platform-building campaign is open now. It's a "mini" campaign, only running until March 17, but the mini-ness makes me happy. I'm less likely to get worn out by the whole process of being a blog-socialite when the party doesn't last as long.
The platform-building campaigns are very much like little parties. You show up, get to meet people with like interests, chat, get to know each other, maybe make some friends.
Take a look at it here if you're interested.
