The first blog story project was nicknamed "Junk in the Trunk". The second, about items sold at police auctions, was called "Going Twice". True the third may not need a tag since the stories had to do with blogging, but Blog Project 3 to me sounds too much like Untitled Woody Allen Fall Project.
I invite you to comment with more creative names for the project, and Bryon and Dave can decide which they think works best. My suggestion is "Blogging For Trouble".
