I thought it'd be fun to see how some of you keep your computer organized. Do you follow some general scheme, keep it arbitrary, throw everything on the Desktop or in Downloads or just abuse the search bar?

Feel free to go as general or as in-depth as you want.

Have you watched any TV shows recently you want to discuss? Any shows you want to recommend or are hyped about? Feel free to discuss anything here.

Please just try to provide fair warning of spoilers if you can.

I'm a sucker for languages and lately I've been wanting to learn a sign language (not specificallly ASL as I put in the title, I'm open to learning any local flavour).

And well, with COVID and everything, I figure this may be a good opportunity to do this with someone else and have someone to talk to. So, is there anyone on Tildes who would be willing to have regular informal video chats, where we talk and you try to teach me as we go? (And of course I can accommodate by text if needed)

No hard commitment, this can just be something we try once and if it's boring for either of us we don't have to continue :) But I'm hoping it'll be fun enough to be a regular thing!

PS. I can teach you French in return if you are interested!
