Question: If I get a comment from "From Review" does that mean it has some official significance, or could that be more or less any user?
Meta-question: Whoever "From Review" is, do we feel that he or she should have at least a minimal understanding of the topic before concluding and complaining that an Answer does not answer the question?
Related question: Say user U asks question Q about topic T, and then it develops that U really doesn't know the most basic results regarding T. According to our policies, is it better to (i) encourage U to learn something about T or (ii) explain in detail the elementary results that U seems to be missing?
Based on all the "what have you tried?" stuff I would have thought the answer was (i). But:
Context: Q&A here. The first version of the answer was just the first sentence of the current version.
"From Review" claimed that this did not answer the question. If From Review is going to say that it seems clear to me that he or she does not know anything at all about Banach algebras - if so I don't feel he or she has any business commenting on whether an Answer answers the question or not.
I mean I could look at any Answer to a question on any of various topics and claim it did not answer the question.
(For readers who know nothing about Banach algebras: If you look at the theorem I added to the answer I believe you'll agree that the first line does answer the question, for anyone who knows that theorem (hmm, we should also note that in this context asking about complex homomorphisms is precisely equivalent to asking about maximal ideals). You have to take my word for the fact that the theorem is a completely totally standard part of Banach Algebras 101.)
