website updates

[Brad Fitzpatrick]

I added a note about memcached vs. shared memory, after recently reading
somebody on a mailing list debating between the two:

   http://www.danga.com/memcached/

And also a users page:

   http://www.danga.com/memcached/users.bml

If you're on the users page and hate your description or want to be
removed, let me know.  Also, if you're not on there and use memcached,
let me know.

I want to link the CVS browse page for the CONTRIBUTORS file, but I can't
decide where to link it from.  Suggestions?
