I do not see how this improves things. "I know that this is perhaps not the best possible answer" now becomes "I know that this is perhaps not the best possible option", this remains a opinion-based question. Sadly, this is a limitation of the format chosen by StackExchange that it does no suits open questions (and they want to keep things this way to differentiate themselves from other similar websites and forums). Even good and interesting open questions remain open questions where it is difficult to formulate a definitive answer and, therefore, do not match the Q&A format.

For the most perfectionists among us, you could also "link to that user's profile rather than just stating his/her name (since user names are not unique)" (never noticed such practice in real-life though ;) ).

Note that while the '@' symbol might be a good typographical convention to highlight that your are referring to a SE user, no notification will be actually sent to the user this way (this is only supported in comments and chat messages, not in questions or answers).

@JanDvorak Yes, but even that does not necessarily prove any bad intention, merely a lack of knowledge how SE works which is to be expected with newcomers. "I just discovered a really neat tool which saved me from big trouble, I would-like to share it with the rest of community" -> this OK, but the next action, once enough reputation, is to go on the chat, not try to find a question more or less matching the tool ;).
