Is there an RSS feed that's just based on a user's reader or wish list?
I know there's that Yahoo pipe one, but the site that hosted the base-url is now down, so it's likely that, that feed will never work again.

make one using yahoo pipes, i made one for the autors, so to change it to a user list must be easy, heres the pipe so just change it

The only problem I have with that is the log-in portion, I can't find any tutorials for it

use the public url for the list

this meas u have to make the list public

Just put your public list url and generate the rss feed.
