Blogging has done one thing well to me and that's the reason I blog regularly. It helped shape my thinking well. Often when you have an idea it can be vague - formless. Writing it down gives it a good shape and setting it in stone. It's also not a magazine where every fucking thing is edited, you have the will to write whatever you want, however you want.

To summarise, discover your communicative personality and help set your ideas in stone.
