#FediTips (or perhaps #FediWarnings?):

Something I discovered the other day on accident is in Mastodon and derivative software, if you are sending someone a DM, and you spontaneously tag someone in the middle of the message, *that person now has read access to the DM in which they're mentioned*. This is a neat feature if you're using it on purpose but could be awkward if you're just trying to link an account and suddenly that account can see you talking about them…!

Apparently this is a Mastodon-unique behavior and was not part of how messages worked in the original ActivityPub. (I don't know if it works this way on independent Mastodon reimplementations such as Pleroma.)
@mcc ooh thanks for this... slack has the opposite behavior, and so has been encouraging this potentially bad habit for me. "If a member is participating in the DM, the member will be notified. If a member is not participating in the DM, the member will not be notified." from -- https://slack.com/intl/ja-jp/help/articles/205240127-Slack-でメンションを使用する#ダイレクトメッセージ(dm)-1
@mcc I have always thought that the dm's are really badly implemented since they are just toots that nobody else can see. I feel like a better alternative would just be to either join with matrix to create chats between users or roll a non activity pub dm system

@CEbbinghaus I think from a UX perspective it's really neat to have the "toots" and DM in a single feed with a single interface. I think that's better than Twitter DMs. "Take this to a side discussion".

Obviously having encryption on protected content in Mastodon would be great. However browser E2E encryption is problematic and it is not the mastosoc devs' core competency.

Integrating matrix with masto is interesting, but once you do that do you need Mastodon?

@mcc Well that is kinda what a dm is. A side discussion. So I believe it should be treated as such. As for if mastodon would be needed if matrix was integrated into it; Of course it would. Matrix is purely 1:1 or group chats only to select people so it would be the perfect drop in for a chat system within mastodon. The problem is that every account has to be 2 accounts and they are completely different protocols

@CEbbinghaus I mean, I don't want a chat system, though. I want to drop a reply into a Mastodon thread with visibility restricted to my conversation partner.

So if Matrix had messages that were adequately durable to be like a thread rather than a chat, haven't we basically reinvented Mastodon in one of the steps to reach that point?

@mcc worth knowing! A bit like accidentally hitting reply all…
@mcc that's one of the reasons I added the css to highlight the DM's in my feed
@mcc yeah, DMs are more like private threads on discord (for now), just for those mentioned. Is good to know that more people can be added later
re: LB: this might feel super obvious to you if you're used to masto, but just the other day I witnessed someone tripping over it and it was awkward. so uh, just in case someone new hadn't seen it yet – now you know!
