Probably the best way to reach me on a one-off informal basis.
Also the easiest way to get updates/nonsense from me day to day.
If you want to contact me professionally, or at length, this is probably the way to do it. I'll respond quickly to most honest correspondence, but don't cold-email me about your cool product.
Please include where I might know you from in the mail if we haven't spoken in a while! Things can get awkward otherwise.
I used to have a comment system and forum. In retrospect, it resulted in more noise, fractured communications, and was another place to endlessly refresh on the internet.
For now, comments are better directed to twitter, or one of the other forums I regularly read. I'll review this choice every now and again.
