Probably less than 10% of DC shows get posted on the just announced thread anyway...
most if not all of the open-mic, singer-songwriter, cover band, etc shows aren't announced in JA, and i'm OK with that.
the important thing is 99% of the shows that are announced in JA are DC shows. it's not the completeness of the listing that counts, it's the fact that you can go there for DC-only information. the noise from non-DC shows is pretty low. i like that.
