I've just made my personal bzr repositories publically available so that anyone can easily get to them (including me!) and so I can refer to things from blog articles. The repos are available for branching using bzr under http://freshfoo.com/repos/ and in human browseable form. See also the links in the left sidebar and in the code section of the site.
I'm using Loggerhead to provide the web viewable form (proxied via the main lighttpd server). It was very easy to setup (using serve-branches). I just wrote a simple init.d script to ensure it stays running.
