Great point to bring up. Whenever I come across a font-identification question, I always try and clean it up by making sure of three things:
- A screenshot of the font in question is available
- There's a descriptive title
- It's appropriately tagged.
Screenshots
This is rather easy. If it's a new user, I don't mind adding it for them and leaving a comment saying "hey, next time include a picture to make it easier!"
Titles
These types of questions can almost always be categorized as "reusable" and "throwaway". Any sort of font identification within a logo could potentially be reusable. Perhaps someone else is searching for the font used for Google's logo. In that case, an appropriate title would be "What font does Google use for their logo?"
"Throwaway" questions are where things get a little hairy. A screenshot of just a line of nondescript text is really unlikely to be utilized by anyone besides the original question asker.
I'm not sure it's the best course of action to outright forbid these types of questions, but we should still improve their searchability. In the past, I have just added in some or all of the text into the title and maybe try to describe it, such as "What font is used for this sans-serif sci-fi text ("lorem ipsum...")". In the rare case that we do get a duplicate font question or if someone needs to refer back to it, this will make it easier to search for.
Tags
These kinds of questions are rather notorious for "tag spam", users will often just throw in any tag that they feel is remotely relevant just because they're allowed to use 5 tags and want to fill them up. typography, web-fonts, typefaces, and font-face are all commonly abused tags. They can sometimes be relevant, but they are often not.
I think it's helpful to add serif, sans-serif, or any other font category tag to help with searchability. If it's a logo, then logo can be helpful too. I'm not a fan of adding fonts to these questions, I usually remove it as it seems incredibly redundant, font-identification already takes care of that.
