All files open OK for me on libre office so far.

Also there's office online, btw, for emergencies.

Calling Syncthing perfect is an understatement.

This is the first time I ever hear of Usenet... read a little... but honestly sounds freakishly scary... torrents are anyway filled with malware... and now we have to trust a centralized source for files?

Do clients that use Usenet verify public torrent file hashes? How is security handled such that I know the files aren't infected compared to whatever the same torrent offers?

It's still a proposal. Nothing concrete yet. But from the looks of it, you can't play such games since it's cryptographically verified.

If you're watching YouTube 10 minutes a day, then it doesn't make sense for you. Cost/benefit analysis should be done.
