Tim Bray has various thoughts on counting RSS feed subscribers and why this will come to pass and how best to do it.

This is an old discussion that's largely been done with regard to user stats for web pages. There are now recognised ways of identifying unique users and so on. RSS Aggregators are slightly different beasts from web browsers but I really see no reason why the existing metrics aren't good enough, especially as the people that actually care about user figures already use them.
