Stack Exchange network consists of 183 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.
I see that the only allowed characters in tags are letters, numbers, _, and @. While _ apparently serves to visually separate words, why is @ included? Does it have any special meaning, or a typical use case?
