Haha, no, I just can't remember all the tags sometimes.

comment Is there something like “Noncommutative geometry internal to a category”?
I don't know much about $\ast$-algebras, but one can certainly do things like non-commutative Galois theory, descent theory and deformation theory by working with corings and comodules.

comment Monoidal Forgetful/Free Adjunction for $E_2$-algebras
Fair point. So perhaps we should only ask $U$ to be lax monoidal?

comment $S_k(x+y)-S_k(x)-S_k(y)$ where $S_k$ is symmetric polynomial
But yeah, similarly to what Alex said above it may be useful to think about the cohomology of $BU$ or something.

comment $S_k(x+y)-S_k(x)-S_k(y)$ where $S_k$ is symmetric polynomial
This looks like the image of $S_k$ under the coboundary operator on Hochschild 2-cochains of the additive group of $\mathbb{Z}$, I think. Hmmmmm... but I don't know of a closed form.

comment Difference between coherent nerve of simplical model category and simplicial category
@AaronMazel-Gee thanks! But what if we only look at the underlying simplicial category of a simplicial model category? How does the coherent nerve of this category relate to the other constructions?
