Here's what I've been working on this week: a Discord RPC server clone!
While I was planning and working on a revival of XMPP's User Gaming XEP, the problem I've encountered while doing so was that there would be very little adoption by programs due to its minuscule market share.
So, I thought: why not just pretend to be Discord to programs and then fetch their rich presence status that way! (none of this actually requires a Discord account, therefore no ToS or bans to worry about)
