Have you tried out Google Schemer yet? If you've not heard of it - there's a fairly ridiculous introductory commercial to get you interested. The general idea is that it provides ideas for activities - but, thus far, the implementation is just based entirely on lists from friends. I kind of thought this would be an opportunity for Google to cull a bunch of data feeds about events from a localized area and aggregate them into options. Instead, it's a place for you to set a vague goal for yourself and check it off when you're done (though tracking progress on said goal is not an option).

Long story short, if you haven't tried Schemer yet, don't beat yourself up - there should be no rush to get in on the ground floor.
