Hmm….
1.) Fragments = 1-150 characters
2.) Signature = 0-250 characters
3.) Blog = 150+ words
4.) Thread = 5+ words (maybe this one so the limit in a thread is like, a five word question/statement)
Maybe changing the blog limit from characters to words should take care of it. I guess a gap will hae to be there, but either way people have about three choices in what to post: a short blip about something (Fragment), a quick statement, question, or point of matter (which could be a thread), or a full-out blog. There you have short, medium, and large. There is no medium-large or medium-small, and anything bigger than large just gets treated as large since there isn’t anything else.
