RSS feed rendering issue in Slack

Slack's RSS feed reader does not render https://clojure.org/feed.xml properly. Some HTML tags are truncated. I think it would be a good idea to make sure the feed renders well in more places.

Reproduce

I have subscribed to the feed in https://clojurians.slack.com/archives/C076654T2LD/p1717409306089639 by seding this message in a Slack channel. Need to wait for the next blog post.

/feed add https://clojure.org/feed.xml
/feed add https://aws.amazon.com/blogs/aws/feed/

Solution

Here are some other RSS feeds that render well in Slack:

• https://aws.amazon.com/blogs/aws/feed/
• https://blog.rust-lang.org/feed.xml

It might be worth experimenting with JBake templates (which are excluded via .gitignore). At the moment, the full blog body seems to be included in the <description> tag, but the feeds that render ok in Slack keep the description short and wrap the blog content inside a <content:encoded> instead:

The content:encoded element can be used in conjunction with the description element to provide an item's full content along with a shorter summary. Under this approach, the complete text of the item is presented in content:encoded and the summary in description.

Start with the generated https://clojure.org/feed.xml and the JBake templates mentioned in the issue; check .gitignore for how generated files are handled. Compare its description structure with the AWS and Rust feeds, then verify the revised feed in Slack. Done means the blog content renders without truncated HTML tags.
