Since 1995 nearly all of my professional work has been enabled by, and published on, the web. This page collects pointers to writing, software, audio, and video.

The present era

I'm working for Hypothesis on an open annotation layer for the web. My posts on the Hypothesis blog are here.

The Microsoft era (2007-2014)

In Jan 2007 I joined Microsoft as an evangelist. During that era I produced interviews and podcasts, advocated for the Open Data Protocol, and created the Elm City calendar network.

The InfoWorld era (2002-2006)

In 2002 I joined InfoWorld on a mission to explore and extend the blog medium. During this era I expanded my repertoire to include audio (podcasting) and video (screencasting), documenting my progress on my InfoWorld blog and my Prime-Time Hypermedia series at the Oreilly Network.

The freelance era (1998-2002)

When CMP bought and killed BYTE, I went independent. I wrote Practical Internet Groupware, worked as a consultant on a variety of web projects (including Safari books online), and freelanced for a variety of print and online publications. Toward the end of this era, blogging emerged and became my primary literary form.

The BYTE era (1995-1998)

I started at BYTE in 1988. During the pre-Web years, I wrote reviews and features for the magazine. In 1995 I switched into Web mode, created, and documented my progress in print and online.
