# Change in computation of “Announcer” badges?

I just received seven Announcer badges in math.se (plus one in MathOverflow) ... Coincidence? Was the method of computing them changed? A whole bunch of people suddenly followed all my links?

Announcer: Share a link to a post later visited by 25 unique IP addresses

• I also received 13 badges simultaneously (6 in Mathoverflow, 7 in MSE, at the same time.) – Hanul Jeon Dec 13 '19 at 4:44
• FWIW I earned 39 Announcer badges and 2 Booster badges :-/ – Jyrki Lahtonen Dec 13 '19 at 11:59
• I got 43 yesterday, and four "booster" yesterday, and another one of each today. – MJD Dec 13 '19 at 14:05
• I've never understood the Announcer, Booster and Publicist badges. What is meant by sharing a link? – Peter Phipps Dec 13 '19 at 15:20
• @PeterPhipps If you click on "share" in a question or answer you get a link which is unique to you, and SE counts the number of "hits" on that (essentially identical) page. For example, if I click "share" on this question I get the link math.meta.stackexchange.com/q/31007/10513, which is the question ID https://math.meta.stackexchange.com/q/31007/ followed by my user ID 10513. So when you click on "share" the URL you get should be math.meta.stackexchange.com/q/31007/15984, as your user ID is 15984. – user1729 Dec 13 '19 at 15:33
• @user1729, thanks very much. – Peter Phipps Dec 13 '19 at 15:43

Some people wondered about the same question also on Meta Stack Exchange: What's going on with the Announcer badge?, Suddenly getting “Announcer” badges every few minutes?

• @DanielFischer well, the bookmarklet does a bit more than that. It gives me the link of the form [title](url) with the title of the question, or [selection](url) if I selected some text on the page. For example, if I use it on this question, I get: [Change in computation of “Announcer” badges?](https://math.meta.stackexchange.com/q/31007) However, it has trouble with titles containing MathJax. (In such cases, I select them first.) Anyway, we can discuss this further in chat if needed. – Martin Sleziak Dec 13 '19 at 12:28
