(Eww...sorry about sending that email with 80 columns rather than 72...)

The problem I experienced with their DNS servers is speed,
specifically, the lack thereof.  There were times I would type in, say,
www.google.com and wait for several moments for the name to resolve.  I
know enough to suspect DNS and so I manually selected two non-Comcast
DNS servers and the problem disappeared.  I switched back to Comcast's
DNS servers and the problem reappeared.
