Would mention alerts be beneficial for the community discussion?
We get alerts for replies, and just about everything else via the community discussion. However, if someone posted on the community discussion and mentioned you, you won't see an alert for that. You will have no way of knowing they mentioned you in their post unless you were to actually go to that post.
What would you think about mention "alerts"?
If you are unaware of what those are, think in terms of Twitter. You'll be notified when someone mentions you in a tweet. It will show up as an alert via Twitter. What if that would occur on the community discussion.
Do you think it would be beneficial?
Let me provide one more example, just incase it's hard for others to understand this specific discussion.
Using an "@" sign we can say use "@everett", or basically any symbol. Once the symbol is used, it would create an alert for the user "Everett".
