P.G.Goerss, J.F.Jardine, “Simplicial Homotopy Theory” prerequisites
I'm certainly not an authority on the topic, but I think for just algebraic topology (i.e. not homotopy theory) one should use a more elementary reference.

Operadic Lift of Lurie's Relative Tensor Product
Okay, and so we use the composition $Tens^\otimes_{\rightY}\to Ass^\otimes\to E_n^\otimes$?

Operadic Lift of Lurie's Relative Tensor Product
@SaulGlasman Yeah, I just didn't know the symbol, so I just called it $Tens^\otimes$

classifying space of orthogonal groups
Ah, @Qiaochu has given a much more helpful answer.

classifying space of orthogonal groups
there's a lot to mention here. Do you know what a spectrum is? If not, it might be good to look up "infinite loop spaces," "extraordinary cohomology theories" or "complex Ktheory" to get moving in that direction.

@DavidWhite Ah okay. Well, I can't answer my own question quite yet I don't think. Anyway, I'll give it some time, in case someone else has a better answer.

I suppose it'd be better if @Aaron could come answer it. But apparently I can't ping him from here.

@DavidWhite I don't even know how to turn a post into a Community Wiki, much less accept a comment as an answer.

I believe that Aaron's comment in the chat room answers this question: chat.stackexchange.com/transcript/message/25359959#25359959

Iterated Homotopy Quotient
this is the situation I'm thinking about. And I'm trying to see if the map $B(G/H)\to C$ can be $E_n$ if, say, $BG$ and $BH$ are, which seems to require some special property of the Kan extension preserving this structure.

Graded Hopf algebras and Hspaces
One can get lots of noncommutative Hopfalgebras from loop spaces, but they'll always be cocommutative.

Why does strong convergence of the EMSS imply that Tot commutes with suspension spectrum?
@CraigWesterland Oh SNAP! Thanks Craig! :D

@CraigWesterland it looks for that you still have to check the lim^1 term. Is it obvious that that vanishes?

From looking at a few other references, it seems that this has something to do with the vanishing line you get in the EMSS when you have strong convergence...
