I think that would be cool tbh. Although the more I've been thinking about it over the last couple of days the more I'm remembering all the various barriers to entry that make it hard on a web interface, I still feel that 1) I don't know that any are straight-up insurmountable, as opposed to nobody having had much motivation to surmount them since like 2005, and 2) everybody doesn't need to be on it for it to be worth being on. But you do need a minimal supply of new blood.
Do you have specifics or links on what form that mini resurgence is taking?
