e-mail is the most reliable way of getting in touch with me:
robert -at- robertcarlsen -dot- net
you can follow me on twitter, but that seems to be more of a broadcast medium:
i occasionally post photos to flickr as bionictechnophobe, although my pictures usually languish locally on my hard drive.
of course, i always welcome comments, and am usually alerted quickly when new ones come in. otherwise, i spend a lot of time at ITP in the east village, nyc and at home in brooklyn or visiting philadelphia.
