I think making newsletter involves an effort, hence it's on the backburner and not used very often. But Skeeta makes that effort, if a bit too IC'ly, but that doesn't mean you can't just send them out. It does a somewhat good job of describing what's going on, so why not? Easy effort, a little nudge to subscribers, someone might get an urge and login. Even if it's five people, it'll still make a difference imho.
