Blogger has an official android app so you know I have to try it out right?
Thing is, I was just thinking of starting another blog (another one!?. I know, right?). Blogger was probably going to be my platform anyway. I love tumblr's simplicity but the blog I have in mind is more substantantive, if that's the word I want, then I think tumblr can handle.
If this android posted post looks nice it might be the deciding factor.
