Shout out to Giacomo's twitch streams. He has taught me about some features of Gleam, Rust, and on top of that he's just a very chill person. He takes time away from his focus to answer questions politely and without judgement. There are dozens of programming streams where the streamer forgets to leave their ego at the door and he is not one of them. I highly recommend following it.
The Gleam community is generally very very nice. I maintain about 200k lines of Gleam[0][1], and they have generally accommodated even my stupidest posts on Discord.
The language itself is as welcoming. Even LLMs are less cranky and output nicer code, not having to deal with React.
