This is exactly what we are doing in toostis.com. We try to create a one-in-one tool for sharing this kind of information with your interest circles (that we call "tribes"). Currently when you log in and start attending events the recommendation algorithm learns about different social groups you belong to.

One needs to consider three approaches of forming an interest circle: shared (an explicit list of members), individual (each user maintains several lists of his friends) and automatic (extracting subgraphs of user relation according to attendance).

What we are currently willing to provide is the combination of them all. Automatic extraction is fun to play with, but you always want more control over it. We are also preparing to launch something similar to the shared model, where you could subscribe to an organizer which is basically a group of related events.
