They wanted to know why we do it, among other things.
Here's what I said:
O blogging how do I love thee - let me count the ways.
I blog because it makes me think. The blog needs constant feeding, so I need to keep thinking and reading and making things up.
I'm constantly looking to make connections between disparate things, to package them up into posts. Finding patterns. Or creating them.
It's a place where I can think unfettered and get feedback on what comes out, from people who I know are interested in the same sorts of things, otherwise they wouldn't bother.
It's writing but it's not solitary.
It's a place where I can do whatever I want with words.
