## Issue
`https://github.com/lbryio/lbry-desktop/issues/6369#issuecomment-882081892`
## Changes
- Replace 'feed' with 'node-rss' for itunes spec support.
- Replace content type from 'rss+xml' to 'xml' so that the browser will display it nicely using the document tree without us having to re-format it ('node-rss' does not). Seems like all feeds that I found does it this way.
- There is no need to escape characters now that 'node-rss' does it. Nice.
## Issue
5951: OG messed up if `$"` is in title
The replacement string would contain `...$"...`. The character `$&` has special meaning in `replace`, so the output was messed up.
## Approach
Use a direct slice approach. A bit less elegant.
- Moved the thumbnail from 'enclosure' to 'description' by appending the thumbnail in front.
- Generate enclosure for media. It's up to readers on how they will handle it. Some will display the inline video player, some will just provide a download link.
## Changes
- Change to canonical_url (with ':').
- The old format of 'claimName/claimId' needs to be supported still, since we shipped with it.
## Notes
- It would be nice to use regex instead of 2 separate paths, but I couldn't figure out how to make the koa variables work.
## Issue
3779 RSS feed for channels
## Initial implementation details
- RSS only (not atom)
- Grabs latest 10 entries (Beamer have concerns)

Even with the caching changes, a 150kB thumbnail still takes 1-2s to fetch. This impacts the score.
## Change
(1) Start with a large-enough placeholder image (has to be larger than the final image -- inflating doesn't count), then delay just enough for scoring, then switch to the real thumbnail.
(2) Since we are now doing post-mount stuff, we have the exact dimensions to optimize the claim thumbnail. This reduces the typically-several-MBs thumbnail to kBs.
