If this @mention thing were to become a problem in the future, maybe it could be remedied with a stickied "Do Not @" list for all to see. Violating that list would result in a warning, first. Perhaps that could be a good fix, should that happen?
I'd be okay with that because I think it would work well for all concerned.
That sounds good. If it could be done, maybe the best option of all would be to let members be able to turn off the @mention function themselves, in order to not be mentioned. That would likely be the est remedy... if practical? A list would be the next best thing.
Hm... I'm not sure. My stance on this issue is making very well-thought-out posts on various issues, and then use massive @Lists to kindle the fires of a good discussion. Extreme bias in favor of using the "@mentions" aside, it's tough to brush off how those members who don't want to be mentioned feel about it. It's sort of reminiscent (a little bit?) of telemarketing. If some people don't like being bothered by the calls, they can and should be able to go on a "DO Not Call List." Earlier during this discussion I didn't really care about their concerns, but having been mentioned quite a few times (it didn't bother me), I can understand how those who get annoyed by it would feel over time.
Would it be fair to say it'd be considerate to keep their wishes in mind? My SOP is to construct a relatively decent OP. Afterwards, create an @List. Then, after that, assuming the "Don't @" list exists, compare and subtract those names. They may not know of your consideration, but methinks they'd be grateful if they knew you had their wishes in mind. I can see how it'd be annoying, especially if the frequency and rate is magnified. What we may all be able to agree on is that the function itself is extremely valuable if used to promote meaningful discussion. Bar none. It's the best function imho.
As to if and how to go forward, with these various things in mind, hell if I know. Staff'll deal with this as they see fit.

It's already become a nuisance for me. I have asked posters to please leave me out of it all. I don't go to the threads. I feel a little guilty because some very good people [read well-intentioned] have @mentioned me.

But I have to walk the talk.
That's understandable. If someone asks someone else to not mention him or her, that, at the very least, ought to be respected.
