dathan...
given that you work at friendster, aren't you kind of restricted from commenting on how
one would go about creating/implementing this kind of system??
if you aren't and you have information to share, then we'd appreciate hearing it!!!
regards,
bruce

We have our own storage engine that talks an API to our own C++ server
that stores the graph. Doing it with a pure myISAM engine is possible
but it's way to slow. Doing a self table join or subselect is really the
only way doing it, less you want to have some application logic that
issues 1000s of selects.
