I think we should add some more description in the pages as currently we get not so nice cards when sharing links. Example on https://community.rstudio.com

@dragonstyle does description needs to be set on a per .qmd basis for this ?
Should we set one global as discussed in quarto-dev/quarto-web#200 ?
Once in one of the tool, we added a feature to generate a defaut description based on page content (getting all the text and creating automatically a summary with the first N words / character. Not sure if this is a feature that would be interesting to have.
