New Tags

Perhaps you should read his previous posts where he gives many examples.

I'm sorry if I'm coming off as trying to aggravate here, but I really don't get it and I'm kinda confused here. The only post of Eos' that I can find is this:

Current events; post the story, keep your own thoughts on the matter hidden except to someone else willing to share their thoughts.
Site Discussion: post your idea and keep certain aspects of it reply only
Shenanigans obviously has abusive uses for it.
Speakeasy, similar to current affairs, except instead of a news article, your own whatever you want to tell about & talk about.
Shady Tree, separate your commentary on the story from the actual story
forum games, keep stuff hidden from people who aren't actually playing the game. or haven't started playing the game.

And while these are neat ideas, doesn't answer my question. Why is this necessary in the first place? Why do we need a method to try to stop people from reading? It's not like it's going to stop anybody from getting to it if they want to, all they'd have to do is make a minimal-content post once in the thread. It isn't going to prohibit anybody, and all it looks like it would do is encourage people to post for the sake of posting so they can see others' posts. Really, why would you want to hide your posts in Site Discussion? I mean, the text under the forum says "Site related ideas and commentary go here", wouldn't it be completely counterproductive to give things posted there any less exposure than they already get?

Almost all of those ideas can have the same result reached through usage of regular spoiler tags, and with the benefit of not hiding information from other users. If I wanted to say something and separate my ideas from my source content, I'd, you know, just use formatting or something. Put my separate stuff in spoilers/hover spoilers, put my source in quote tags, or heck just put a big 'ol line of dashes between them. What I wouldn't do is make it so people coming in are unable to see any discussion points I'm making.

I'm not trying to be all smug and argumentative, I am legitimately trying and failing to think of a situation where using [HIDE-REPLY] tags would be more effective and helpful than what we already have. Is there any other forums that uses these that someone could point me to so I could see them working in action or something?

Ninja edit: You know what, never mind I won't drag it out any more. Sorry. Basically:

meh, in the end if it's useless it won't be used, if it's useful it will happen
