Is it appropriate to use comment section to refer to a specific user who is most likely to provide an answer? For example, when there is a request for the IUPAC name, one might want to type
cast @Loong (or
sudo summon @Loong:) ), because this is the person who is most likely to provide one of the best answers (no offence to the rest of you guys).
Would you say it is a good idea, or rather an inappropriate one?
In one hand, users are utilizing their favorite tags in order to receive notifications regarding the questions of interest. The problem is, when a new question is posted, it is quite often insufficiently/wrongly tagged. Also, for the interdisciplinary questions tagging may not be the best selector.
In the other hand, it breaks the core SE philosophy in regard that individuals are free to invest their time and will in solving particular problems, and it might be considered as if they are forced to do so.
