Yeah RP via Twitter is super hard! I felt like I couldn't figure out what I wanted to say because I always had sooo much more I wanted to do/say than what I could put into 40 characters. ;(
I always ended up having to double or even triple my posts because there was just so much I wanted to do, even then, I couldn't say everything I wanted to in that amount of space.

I also prefer paragraphs for RP, however, I don't believe in making long posts just because I can. If I don't have that much to say, I won't just make a post long for the sake of maki a long post. XD

I see you already have a partner for the Reverse Fairy Tale! I'm going to review your other options of possible RPs and see what else interests me. :)
