Is Twitter the new Blogging?

A question that has undoubtedly been asked before by much shrewder minds of the 2.0 generation.

It occurred to me earlier that I have hardly blogged of late, and that's probably down to two things:- a) I haven't really done much that warrants a blog post (not that that usually stops me) and b) Twitter. It seems that a throwaway sentence of less than 160 letters can replace a blog post of 160 words plus quite adequately.
