I understand how slash vids, etc, fit into that category but for me they're not enough;

yes! I don't want to eliminate slash vids, or male character-focused character studies; I think there is room for what we all need in fandom; but those vids alone are not all that I need.

I keep fantasizing about a political/feminist-sf vidshow at WisCon...

yeah, I wanted to do one this year, but the people I talked to didn't have time/resources this year. Maybe 2009.
