Jesus no. Please, just no. There is a reason why people are favoring Discord, Slack, Facebook Groups and whatever else over the old strongholds (mailing lists, IRC):

- anything email based (including usenet) requires you to expose (at least) your email address to the general public, meaning you will get hounded by spam

- mailing lists (by design) have to break common anti-spam schemes and it's difficult to get the workarounds done correctly, so you'll end up fighting your spam filter all the time to read the emails you want to read

- mailing lists require strict moderation to avoid people abusing it for spam, which leads to issues when the sole moderator goes off on holidays and no new mails come through.

- mailing list management tools are often enough a pretty horrid/inconsistent mess

- for each mailing list you join (and want/need to stay in longer), you have to setup folders and filters in your mail client/provider, and you have to follow the incantation of the specific mailing list to opt out, whereas IRC and Discord make organizing and leaving easy

- mailing lists and many IRC channels end up being publicly indexed in Google which may or may not be in your interest

- many mailing lists and IRC in general restrict incoming content to plain-text or limit file sizes which means it's hard to enrich a question with screenshots, videos or binary files.

- mailing lists are asynchronous and don't support different modes of communication that do not require exposing your phone number publicly - it's not (easily) possible to have a quick call to quickly solve an issue, yet a 1 minute phone call can transport much more density than wasting half an hour playing email ping-pong

I'm sad about IRC though given that there hasn't been any major reaction to Slack and Discord, which led to an erosion of its userbase and then the final implosion of Freenode.
