I mean that if I think I am "master" in some topic or tag (iOS address book, localization etc.), I wish to get an alert when a user posted a question tagged with a specific tag. Is there a way?

  • Should work somehow, they have it in the chatrooms (for instance for C++).. – Default Jun 10 '11 at 10:52

You can do that by subscribing to the tags you are interested in, thus getting email alerts – you can subscribe from the tag mouseover.

tag mouseover

However, if you're familiar with RSS, I recommend to use the builtin RSS feeds, since you can do that not only for single tags, but also for some boolean combinations of them: see this blog.SO post.


Another way is to feed the topics to a slack channel.

Suppose you create a new team in slack

After you login the slack team, go to one channel and run below command to add a new topic linux in it.

/feed subscribe http://stackoverflow.com/feeds/tag?tagnames=linux&sort=newest

Then you will keep getting new questions about Linux from stackoverflow.

You are fine to add any topics which you are interesting with below format: http://stackoverflow.com/feeds/tag?tagnames=<TOPIC>&sort=newest

run /feed help to get help.

    Why do this on slack when you can already do it on stackexchange.com/filters? :) – Jason C Mar 27 '17 at 3:54
  • will you get notification from StackExchange? Emails easily get ignored if you get several hundred emails daily. Secondly, it is my habit to deal with technical questions. So I can send the feeds from different sources to different slack channels. – BMW Mar 27 '17 at 6:44
  • I feel like stackexchange.com/filters is underappreciated and like to plug it whenever I can. :D The filter notification mails are sent from do-not-reply@stackexchange.com. What I usually do for sorting, is use tagged email addresses (e.g. the "xyz" in "myself+xyz@gmail.com") and then I use that as criteria for sorting / labeling. The other thing I find convenient is just an RSS reader browser extension, if I want real-time notifications (the browser extensions are nice because they're always visible no matter what site you're on). – Jason C Mar 27 '17 at 7:37
  • Yes, I know your meaning. But in these days, I don't check email frequently. If my friend need contact me, there are a lot of instant way to do, but not email. Email for me is out-of-day style. Same reason for RSS, it is too old, no fun. – BMW Mar 27 '17 at 8:34
