From purely a user perspective, because I haven’t dug into the tech behind either, I’d probably vote Matrix. Signal is nice but personally I find matrix easier to use for group chats and bigger rooms. I only have 4-5 people on signal and it’s useful for those moments but on Matrix I can find bigger chats to join and jump in and just talk with a handful of people.

I’ve never heard of this before but that looks awesome lol I was playing some older text based games like this from the 80s a few weeks back so I’ll add this one to the list

I will never get over how amazing blender looks lol I just wish I was better at it. Feels like most version updates they push have some big feature improvement
