Suman Park [Korean] wrote today that Wiki-style editing used in Textile might be a great way to write blogs, particularly for moblogging.  While I am too lazy to remember or look up those Wiki-style formatting special characters, I think it does make good sense for moblogging.  Now mobloggers can be really bold.  Maybe they are doing this already.  By the way, Texism blog looks good.  Classic use of whitespace.
