So, I'm doing research for a behavioral meta question about answering Fate questions, and that means slogging through Fate posts on the site for examples and precedents. ALL of the Fate posts.
I can track down about a dozen Dungeons & Dragons tags which are actually used. If I went through them, I'd feel like I'd probably seen every D&D-related post on site. I'll have waded through something like 3,000 posts and may soon perish of Acute Alignment Poisoning (tell your friends about AAP; the life you save may be your own), but I'll feel like I got a pretty complete grasp of the site's D&D catalogue.
In order to do the same for Fate, I have to learn the name of every individual game ever produced using the Fate engine (and apparently there are debates about that; for example, the Wikipedia article which sites this post as its source ignores the post's caveats). It doesn't seem like I could ever confident that I'd seen most of RPG.SE's Fate game posts.
Now, perhaps my comparison is faulty, and I should be looking at d20 System tags instead of D&D tags. But I don't see dnd-4e questions getting answered with call-of-cthulhu-d20 rules nearly so often as I see dresden-files questions getting spirit-of-the-century answers. So if my comparison is faulty, there's a behavioral issue that needs to be addressed about Fate answers and I'll open a meta question about that.
Although the fate tag was never very comprehensive, this meta discussion leaves me with the impression that I now can't even hope for a single tag, or a small group of tags (and let me point out that under the circumstances D&D's round dozen tags are a small number, since they feel comprehensive), that'll let me feel like I can track down all the Fate questions. Instead I have to round them up tag after tag after tag after interminal guesswork-discovered tag and just hope not to go mad over the astonishing number of duplicates that are wasting my time and brain.
Is this correct? Am I missing a search function? Am I misinterpreting that meta discussion? Or should I just suck it up and accept that this is a necessary casualty of the tagging policy?
