Stack Exchange network consists of 175 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.
The random tag seems to attract taggers of all kinds, from using random number generators (which I think is the right usage) to people complaining about their computers "randomly" shutting down.
How should this tag be used?
It's a meta tag at best and now that it's been wiped away, there isn't much to do with it.
I think Random should only be for questions or discussions about randomness and or random number generators , not random events that are happening.
