I generally just let the 313 list be. Frankly it's been moribund lately and probably has more subscribers outside of Detroit than inside; the flavor is completely different than it was 20 years ago. And even typing "20 years ago" about a mailing list feels weird.
I don't know what to think about the Derrick May beefing -- I'm not close enough to any of the principles in that fight to know what's up. I'd rather that the focus stay on music, and to my mind, it's been 30 years since Derrick May's really been musically relevant. There are loads of Detroit producers and DJs who are doing great things now, and I think we've all been remiss to not amplify those musicians. There are vital new voices like Ash Lauryn, who deserve more attention: https://undergroundandblack.com/ And it's clear there's a lot of emotional upset and personal issues that have spilled onto the list. I don't want to say that's not appropriate content, but it should be in the context that we're a group of friends, widely dispersed geographically, with something in common. So keep in mind you're talking to a friend, and they deserve respect even if you disagree with them.
