What other hidden or inobvious RSS feeds are available on Stack Exchange and its sites?

Question

I know about finding the RSS feed icon at the bottom of any "Top Questions" page, giving access to recent, featured, hot, week & month questions feeds. I also know that you can get RSS feeds from tags such as support and even construct searches with specific tag and view combination.

Also, I have just discovered that you can get user responses feed and by inference a full user feed, and even use boolean operators on tag combinations, but I don't know what other user related feeds are available.

As far as I can tell, Stack Exchange only supports the hot questions feed and the feed without questions just returns the same as the hot questions feed. Also, Stack Exchange doesn't appear to support user feeds, which is a shame as that would be even more useful.

So, to summarise what feeds I can identify so far:

• http://stack exchange site/feeds ( e.g.)
• http://stack exchange site/feeds/featured ( e.g.)
• http://stack exchange site/feeds/hot ( e.g.)
• http://stack exchange site/feeds/week ( e.g.)
• http://stack exchange site/feeds/month ( e.g.)
• http://stack exchange site/feeds/tag/tag ( e.g.)
• http://stack exchange site/feeds/tag/tag1+tag2 ( e.g.)
• http://stack exchange site/feeds/tag/tag1+or+tag2 ( e.g.)
• http://stack exchange site/feeds/tag/tag1+-tag2 ( e.g.)
• http://stack exchange site/feeds/tag?tagnames=tag&sort=newest ( e.g.)
• http://stack exchange site/feeds/tag?tagnames=tag&sort=featured ( e.g.)
• http://stack exchange site/feeds/tag?tagnames=tag&sort=hot ( e.g.)
• http://stack exchange site/feeds/tag?tagnames=tag&sort=votes ( e.g.)
• http://stack exchange site/feeds/tag?tagnames=tag1+tag2 (+an optional &sort= term) ( e.g.)
• http://stack exchange site/feeds/tag?tagnames=tag1+or+tag2 (+an optional &sort= term) ( e.g.)
• http://stack exchange site/feeds/tag?tagnames=tag1+-tag2 (+an optional &sort= term) ( e.g.)
• http://stack exchange site/feeds/user/user id ( e.g.)
• http://stack exchange site/feeds/user/user id/responses ( e.g.)
• http://stack exchange site/feeds/question/question id ( e.g.)
• https://stackexchange.com/feeds/questions ( e.g.)
• https://stackexchange.com/feeds ( e.g.)

While the following inferred possible RSS feeds don't work:

• http://stack exchange site/feeds/votes ( e.g.)
• https://stackexchange.com/feeds/user/user id ( e.g.)

So, what other RSS feeds are available?

So far I have been unable to find any canonical list of what is available, just the occasional meta post containing partial information. So far there have been no responses to What feeds are available? while the Community FAQ references a question which is no longer appears relevant (as far as I can see).

Answer 1

This is not an answer, but a way to using these feeds.

I've recently discovered rsstail and multitail, both by Folkert van Heusden. These are utilities which allow you to create, effectively, a "tail" of an RSS feed (for rsstail), or of one or more files and/or processes (for multitail), in a terminal window.

multitail adds a bunch of additional features, including color highlighting (a bit gaudy, but configurable), scrollback, search, timestamping, and other capabilities.

Getting multitail to read, say, a whole list of feeds is a bit complicated, but I've glued up some AWK script which will create an rsstail process for each feed in my newsbeuter URLs file (newsbeuter is an interactive console RSS reader), and follow those. More on that here.

Though if you just want to follow an individual Stack Exchange question's feed, you could run something like:

multitail -CS rsstail -l "rsstail -l \
    -u 'http://meta.stackoverflow.com/feeds/question/151519'"

(That will give you this question's feed.)

For impromptu monitoring of some specific feed or list of feeds, this is pretty handy. Since it's just running in a terminal, you don't have to remember to clear the temporary additions out of your newsreader at a later date, it's intrinsically ephemeral.

Area 51 has slightly different feeds:

• https://area51.stackexchange.com/feeds(+an optional &category= term) (e.g.)
• https://area51.stackexchange.com/feeds/hot(+an optional &category= term) (e.g.)
• https://area51.stackexchange.com/feeds/progress(+an optional &category= term) (e.g.)
• https://area51.stackexchange.com/feeds/beta(+an optional &category= term) (e.g.)
• https://area51.stackexchange.com/feeds/launched(+an optional &category= term) (e.g.)
• https://area51.stackexchange.com/feeds/user/user id (e.g.)
• https://area51.stackexchange.com/feeds/proposal/proposal id (e.g.)

Here, &category=category name can take one of the following options for category name: arts, business, culture, life, professional, recreation, science, or technology.

The following are not legitimate Area 51 feeds:

• https://area51.stackexchange.com/feeds/featured (e.g.)
