Howard, absolutely, I am seeing less and less "I can't see the point of this" and more and more "lots of great stuff in there but I can't keep up". Part of the answer is social filtering and part is automated filtering but I'm thinking there is a third part to it which is controlling flow. I think all of these services are very much in a beta stage. I'm less concerned about "one tool to rule them all" but more a set of things that we can configure to provide what we want.
