actually its more useful in replying to multiple posts/topics/sentences/users in a thread..
see your system is ok if you just want to quote 1 person and reply to something they said +there entire friggin post.. unless you manually edit out the jambo

i'm not sure about you guys but seeing the same post including its images quoted can be silly... so often sensible people split up someones post into multiple quotes and reply to them one after the other.. this is time consuming in that you actually have to write out the whole damn quote tag(or copy/paste whatever is faster) including a username if you want to do it here.. still blind quoting is just as effective.. its not that hard to pickup on who one person is replying to if one just follows the thread..
why on earth you can't just add the tags in for blind quoting so it works at least.. i don't care about the button (although it would be quicker to hit that and have it auto generate the quote tags, so one can just paste text into it), or the popup text box that asks you to stick in the text(heck thats just as annoying sometimes).
anyway having just a blind quote button, or even the tags working is just easier to do, its also better than quoting someone with "blah" as a proper tag quote displays in quoted manner on the final post, makes it easier for other readers to spot if nothing else.
is it really this hard to stick to standards.. and it seems like a pretty standard thing on many other boards actually ..did you guys know that? seriously just about every other forum can manage adding this into it.. come here.. oh no no... were doing things differently around here

oh well food for thought for the next C9 board or whatever yeah.
