Tags were Gargron's idea of switching from forum boards when we got to new site back in the early years of this fucking site. And damn, that idea sucked ass...
Now, I obviously use tags system, having my own tag, which you all should worship, ang actively tagging my threads, in vane hopes that some fucker will search content using it. Which is absolutely vane, because we actually don't have tags search of this fucking site. Yes, got tags, don't have tags search. You can check this out yourself and search... "4th_tag" for example. It has threads, but search returns nothing.
So, tags essentially are only useful when you are ready to go to the tag page and dig through them yourself, which is a crappy way to search for anything. Meaning, in current implementation, they only work to give you quick recap of what thread is about when you already found the thread.
Personally, I preferred when we had boards. Projects, anime, games and other stuff was sorted out to general categories, and random useless shite, which CL users pump out every day, like forum games, were moved to 'spam' board, and we had option to not see that one, which I gladly used.
So there you go. Tags should either be fixed to work like tags, or they should be removed in favor of some actual working system.
Also, really, don't put yes/no voting on something like this. Ask people to write fucking opinions. Just so you know - I didn't vote yes or no anyways.
