Seperate community description from community details in external URL previews

[poVoq]

Is your proposal related to a problem?

When sharing links to Lemmy the URL preview takes the entire content of the community description box, which often contains a lot of info and and more wiki like things such as links to related communities and websites. This makes these URL previews very unwieldy and confusing.

Describe the solution you'd like

I think it would be good to have a separate text input field for a short description of the community that can be used for URL previews and other similar things.

Also and unrelated: might be good to add a very short description to what Lemmy is to these URL previews as a sort of promotion effort.

Mmm I see. We might have to do the same thing we did for the main site description, which is to have 3 fields: title, short description, and sidebar. Currently community has name, title (IE display name), and sidebar.

We either should probably:

• Remove the sidebar from the html tag description, and just use display name.
• Or add a short description field.

TODO: also I see the main site description tags should be fixed too:

That short description should be moved to description.

I think the solution for this is to just take the first line, or first x characters of the sidebar.
