It depends. Usually when articles have an {{attention}} tag, it’s because no other tag quite fits. Whenever I add an attention tag, it’s usually so I can explain my stance in full detail and why I added it. I can see why some articles might benefit for a parameter in the {{attention}}. For example, if measurements for food ingredients are missing (though even that’s a bit of a mouthful, and some people tag that under {{accuracy}} with a message on the discussion page). So I understand the parameter is optional. The issue I have with this is that even if it is optional, it might redirect attention away from the discussion page. The idea with the {{attention}} tag is that people see the full reason on the discussion page, and sometimes others add their opinion on it. If a parameter is added, people might not see the full picture. For example, the article Learn the Irish Language
is currently tagged as needing attention. You could add something like
{{attention|Should point to more resources instead of just translations.}}
, but then you look at the tag and focus on that, but not noticing some words are misspelt (second note on the discussion page). You could argue you could just add that too, but that would be too probably be too much. Besides, it doesn’t give much detail. The person pointing out the spelling mistakes explained why. Also, the person leaving the message about pointing to more resources instead of translations offered more of what would be helpful in the article. If someone just looks at the tag, they won’t see the full picture. Also, how much is too long? Perhaps people will be more inclined to edit the tag than the actual article because it’s easier to point out what’s wrong than actually fix it. If someone has something extra to add, it would be better to add it to the discussion page. People might ignore the discussion page with detailed explanations if a parameter is added. Discussion pages adds to wikiHow’s collaborative effort. Personally, even with slow internet, clicking onto a link to the discussion page is no bother for me. Messages on discussion pages (if they’re relevant obviously) stay there even when the issue is resolved, whereas the tag would be removed, meaning if there was any issues mentioned in the tag that someone left out, you would unlikely be unaware of it due to the tag with the issues mentioned in it being removed. A message on the discussion page would still be there so if a user saw it, even if the tag was removed, they are still aware of it and in the case of there still being an issue, the user can do something about it. This idea could work for some articles, but the majority of articles is found in the Pages Needing Attention
(which links to itself in subcategories?), very few articles have short explanations. I can’t really see a page having a tag saying
{{attention|I am not sure what heterosexuality has to do with men relating to feminism. There are plenty of sexist non-heterosexual men too, so the last part might need to be altered. I also want to try to steer clear of the over-labeling of "mansplaining"; while there are real circumstances of that, I think it's also important to emphasize that everyone gets an equal opportunity to explain something (women can "mansplain" too), but not in a demeaning way. And while "checking your privilege" (a phrase that is overused in the wrong ways today) is real for some circumstances, this makes it sound like men have it always better than women, which incites anger in some men because they think it's not true (I am not saying it is or isn't, but "always" is too extreme). This also needs a step on understanding what feminism is not. It's not a reason to hate men or anything; there are some radicals who do, but that's not what feminism is at its core. (And I get this may or may not change ratings. I'm basing this off of ratings that I think raise legit concerns. People are also prone to attack feminist-related things)}}
All of what is mentioned is relevant, and cannot be summarised in a tag. (That was from Discussion:Be a Feminist As a Man
BTW.) A discussion page also shows who said what, so if need be, you can reply directly to the user, going through an article’s history to find out who added the tag an sometimes be hard work. I just love discussion pages and I think they are really useful, don’t underestimate the power of them.
