I have one, but it's not as satisfying as LJ. On LJ you share your opinion and I respond and we have this great conversation. Tumblr is more like, "here's a picture of a cat!" LIKE LIKE LIKE REBLOG. I miss the conversations. You CAN have conversations on Tumblr but it's more difficult.

So go ahead and get one, play around, reblog pics of cute boys, but don't delete LJ or anything. I'm "imakegoodlifechoices" on Tumblr if you want to find me. :)
