I make no money from blogging, hardly anyone reads my blog and if I ever run/hold a significant public position my blog will probably hurt my job chances. So why blog? I can think of three main reasons.
1) Focus my thoughts – Ideas come through writing and articulating my thoughts can help me give them shape and depth. But I could just as easily do this in a journal, which leads to:
2) Vanity – I can show off on my blog. Because I’m bright but not that bright and want to distinguish myself from the crowd. The blog gives me a place to share what I’ve been thinking about, and to show off how much I read and know.
3) Historical record – I can track my intellectual progress and what I thought was interesting at various points in time.
