While Before The Breakout is the tumblr account I registered with, I’ve created a few other ones:
http://ninesnowboots.tumblr.com is going to be a “personal” tumblr for me. My full blog is more for careful entries (and I like comments), but I’ve been convinced more about what Tumblr can do.
http://fyeahcharacteractors.tumblr.com is going to be a sister site to Before the Breakout, with character actors in different stages of their careers.
http://fyeahsnlwriters.tumblr.com is similar; basically spotting random SNL writer walk-ons throughout the years.
