A few of mine :

• AndOTP : A good app for OTP that actually let's you backup your keys and move them easily and securely to a new phone
• Blokada : A system wide adblocker for Android. 4000000 ads blocked so far on my phone
• YouTube Vanced: Not really a "hidden" gem but a cool app nonetheless. I wish people knew you could get an ad free YouTube experience on mobile. It also includes sponsor block so you really get straight to content. Also let's you get a YT popup player and shutdown the screen with the video still playing.
• F-Droid an Android open source app market. Often includes apps that are not allowed on Google market.

To some extent I think you can do most of that on Lemmy.

You can upload images for your posts (not sure for short videos) and cross-post them to other communities.

Edit: I don't know kbin.social but I suspect it would be more adequate to what you want to do.

Bleak urban funeral home ?

Honestly, I respect their decision but at the same time I wonder why they didn't create a standalone unfederated from the get go.

If you want to keep the community small and tightly nit it's just not compatible with the federation system. Now people got invested in some beehaw communities only to end up disconnected from them.

Still, it's not like there is a guide for this. We are all learning how to make the federation work. I hope we can keep it civil toward instances that choose to defederate.

We are all invested in the same thing: Making Lemmy successful.

Out of curiosity, you say an overwhelming conventional force. Does that mean the NATO plan explicitly says it should be conventional?

I always imagined that if a country nukes another they would immediately be nuked themselves. Because if a country is using their nuclear arsenal, it's probably a bit late to moves armies around.
