I've been thinking a bunch about email and mailing lists recently... about how to deal with them, how to follow the ones that are important but not get drowned in a sea of email noise. I have a non-tech email account which is where friends mail me personally and where I handle theatre-related stuff. I do not receive a stupid amount of email on this account, and I am almost always interested in reading the messages that arrive there. So on my inaugust.com email address, I've been considering unsubscribing from all mailing lists and setting both Launchpad and github to stop emailing me most things.
For Launchpad and github, most things I care about have status pages of some sort: lists of bugs or branches I need to attend to or whatnot. I really don't need to get an email every time someone files a bug - it's noise.
Mailing lists are the trickier one, because so many open source projects are centered around them in one form or another. For a long time I kept filters to file things in to mail folders - but then I realized that I'd forget about large numbers of them and would never read them. So then I removed those filters so that they'd hit my inbox and I'd read the stream - but that's obviously too much.
I'm starting to think that they are all a complete and total waste of time in terms of existing in my inbox. Back in the good old days of the internet, a lot of that sort of conversation occured over NNTP, which thankfully also had the idea of expiring messages from the newsgroup after a period of time. The separation here was really nice, as it separated messages in general from message TO ME. RSS feeds into a feed reader might be an option - but it doesn't model the "Oh, I noticed a thing I should respond to which now needs to be a conversation I'll follow" workflow.
I don't know the answer - but the current stream of crap hitting my Inbox is fully problematic. (And no Stewart, notmuch will not help my problem here)
