For new #users here on #Mastodon:
If you want to #follow people that writes about specific topic, I suggest that you check out Trunk - a service where people can write them selves up on different lists in order to easier find a #community that has the same interests as me.
For example, I want to find more people that writes about #atheism , I can just choose the tag "Atheists" and just follow everyone under that specific category with just a few clicks.
Check it out:

If you want to share a file with a friend or colleague, you don't have to trust a third party service. You can use OnionShare.
The newest version even lets you publish static websites as onion services.

Jitsi is getting a lot of mentions here.
I wonder if people are aware of GNU Jami, a P2P solution.
https://jami.net/
Jami has end-to-end encryption while Jitsi is only encrypted during transit. The Jitsi server has your packets available in unencrypted form. If you can't trust a Jitsi server and need end-to-end encryption, Jami can be a good alternative.
