It's really a shame... I was a member on the original service when it was called ONEList (1997–1999), through the eGroups merger (early 1999), early years of the YahooGroups buyout in mid-1999, then intermittently after that — and all three were far more user-friendly than the alternatives available now. I tried participating on one of the two main alternatives, since a group I'd been on before moved its archive there, but it was just too much of a PITA to bother with.
Also, moderation controls over the list and individual users were available on ONEList/eGroups before YahooGroups bought them out. (I spent far too much time in college in 1998–1999 manually approving messages for a very active 2,000-member discussion group that kept having massive flamewars over stupid things.)
