There also is the empty https://kbin.social/m/WritingPrompts. On Beehaw's writing some people have posted prompts and it's the first place here where I've actually seen someone reply to a prompt. It's not a dedicated writing prompt space though.
In general it looks like the migration is mostly spearheaded by tech rather than art, which I sort of expect. I mean the original /r/writingprompts didn't even discuss or acknowledge the protest at all.
For writing, practice writing short stories using writing prompts (I normally use Reddit's /r/writingprompts but I'm trying to find an alternative here) and post them on the thread even if they suck. The commitment is low since it's a short story and you can afford to twist the story to match your writing style rather than the other way around. You'll also get votes and feedback from other members.
I started drawing as a kid, stopped for a while, and got back to it in my teens since I started doing a lot of writing then and wanted to visually depict what was happening as well. One thing that helped me a lot was to not look at other people's art or photographs but rather solely work with what you're visualizing in your mind and reiterate (with many many strokes) until the quality becomes acceptable. Use pencil and sketch with short and light lines. The point here is to develop your own intuition for perspective, splitting an object into basic shapes, and so forth.
I'll also add that it's extremely important to create your own style both for writing and drawing. Make your stuff look good, but always keep in mind that it's fine to have your own quirks and distinctions. E.g. if your lines are a bit sketchy or if your circles aren't perfect that can easily be part of your style.
Writing and drawing!
It requires no upfront investment, can be done individually, and it's one of the few arts which is constrained by skill rather than budget. You can write a bestseller novel with just your computer but good luck doing a blockbuster film on your own.
There likely will be another flood of users over to Lemmy once the API changes formally occur in July. The mods and power users will find themselves handicapped without their tools and more will migrate.
That's so true as a Linux user in front of non-techies.
I've never used a colo before; my rack servers live happily in my basement. If you google say "1U network colo <city name>" you'll find many providers.
