800+ pages containing a low percentage of useful post and a tonne of useless posts.
Sorry, but unless you can go through the thread, post by post, and explain in each case, according to explicit criteria, that such and such post is "useless" to give us a real percentage rather than uselessly gesturing that that is the case, you really are talking a lot of nonsense.
My statement is my opinion. I have read every post in that thread as it unfolded. You're asking me to back up my opinion. That would be fair enough if you had provided the same for your opinion that the vast majority (please correct me if I'm paraphrasing you wrong here) of posts in that thread are meaningful.
I'll humor you anyway, since it's so easy. Starting from the most recent post, working my way back up the page:

13 out of 17 posts... Say roughly 75% is crap. There you go.
Side note:
https://bitcointalksearch.org/topic/m.11066175 -> Mentioning the argument is off topic. See, I'm not the only one that thinks the thread is cluttered. Quelle suprise!
I'm pretty sure the mods are having loads of fun deleting posts in the new thread. Gotta make those bitcoins BFL paid regularly count for something, huh?
Unfounded allegation. Do you see the irony?
Now where's the thread on Josh vs. Bruno again?
Very useless comment, but thanks for sharing! It would be a shame if someone reported useless banter sentence by sentence to protect the delicate sensibilities of those who have no reading comprehension. Censorship never had such powerful champions until now...
Excuse me for trying to end my post on a lighter note. I don't like being sour. You can have all the sour grapes for yourself if you like them.
