That was a long post back there, so here are my quick high level points countering the notion of meta-crap, which I hope to demonstrate with some scenarios over the next couple days:

1) meta-data on a local, individual scale is interesting enough

2) in many cases, people actually are creating accurate meta-data today

3) even where explicit meta-data isn’t just lying around in the filesystem, meta-data can in some cases be inferred
