I know, I was responding to "Let's provide a tarball of emails for archival purposes (the Internet Archive has up to February 2009)". A tarball sounds like a good idea, but I was confused by the mention of the Internet Archive when the official SL4 archive is still working fine.
My point there was that sl4.org will cost $8+ a year indefinitely (for the domain name alone), and my mental target is 2070; will Eliezer pay >$600 just to keep sl4.org going? Probably not. I'd guess sl4.org will be no more by 2030 at the latest. So it's nice to know that there's an existing backup already even if no one ever gets around to making a tarball dump of the website.
(I've learned to ask for busy people to do as little as possible; if I suggested a dump be made and only then SL4's listserv shut down, I would guarantee that the proposal go nowhere.)
This is probably of interest only to the old-timers here. (Ironically, as a cross-post, this is almost by definition spam for LW, since anyone really interested in the topic would already be subscribed to SL4 and would have seen the emails.)
In 13 March, I finally got around to a long outstanding bit of cleanup: suggesting that the equally long defunct SL4 list be formally closed, things tidied up, and the lights turned out. The suggestion met with a mixed (and muted) reception.
Last night I followed up with a second email comparing SL4 activity to activity on Extropy-chat, LW, OB, and MoR; it won't surprise anyone trying to drink from the firehose here that LW is approximately 3 orders of magnitude more active than SL4 is.
