I have hosted a PeerTube instance and surprisingly the storage is not a problem because it is very cheap these days.

About the bandwidth, if you enable PeerTube's p2p tech (WebTorrent) you can have a fair number of users streaming at the same time (but it's not great for privacy).

I have proposed a network of PeerTube instances to a group of youtubers each with tens to hundreds of thousands subscribers and the benefits/costs ratio looked pretty good to them. It didn't work for other reasons.

Notice that youtubers earn basically nothing from YouTube except those with millions of subscribers. They are on YouTube just for visibility but if enough creators move at the same time they can also move a good percentage of the userbase in my opinion.

Thanks, though the article also says that Telegram states they didn't share any data because they have never stored it (like IP).

Telegram is known to occasionally hand out users' data in extraordinary circumstances

Source? And what circumstances? AFAIK it never happened.

And here it will be harder to abuse your mod powers since there is a public mod-log!

Everywhere, no matter the page, you can write:

- [[Book name]]
  - [[Quotes]]
   - Plain quote here.
   - Another quote here.

or:

- [[Book name]]
 - Plain quote here.
   #quotes

You can retrieve them with the query:

{{query (and [[Book name]] [[quotes]])}}

Remember that queries look for references also in the parent blocks, so the following:

- [[Author name]]
  - [[Book name]]
   - [[Quotes]]
    - A quote.

matches:

{{query (and [[Author name]] [[Book name]] [[quotes]])}}

So you can group your quotes and tag them only once instead of repeating the same tag on different lines.

You can embed the quote somewhere else and style it as a quote using the > symbol:

- > ((block-id))
