That's not hype, if there was any doubt. I don't use Facebook much as
an app, but their contributions to memcached are significant.
I used to be on the memcached developers mailing list, and guys from
Facebook were often the ones leading the discussion, submitting
patches, etc. They were (as of a year or so ago) very active in
driving memcached forward. When people had questions about 'how will
this work at large scales', it was often someone from Facebook who
would chime in with 'well, we did it this way on our x-million 128GB
cache servers' or some such. This was both for hardware/architecture
questions, as well as development techniques in coding for a
distributed RAM cache.
