I run a key server, which allows me to do as many key-retrieval queries
as I like, without giving any information away to the rest of the
world.  It also helps a little, but not completely, with the problem of
adding keys to the keyserver network, with respect to my social
network.  In particular, it's not easy for any keyserver to see which of
its peers' peers a given key or set of keys, originated from.  However, 
in theory, an attacker could track the progress of a given key across
the network of keyservers by quick querying, but it's a pretty small
window between the introduction of keys to a single member of the pool,
and it being shared to all the keyservers.
