I think many rss readers that parse the index html searching for a rss
link are checking for the standard `application/rss+xml` or
`application/atom+xml`.
Thanks a lot for caring! I applied this, as I agree after some searching
that it seems to be the (more) recommended approach.
If you were having trouble with a specific feed reader before, please
try again, and let me know if there is still any issues.
