CIS-2021 in Moscow – is it worth the effort?

Roma, you missed the word "if" in the context, and all the other words. The main point here is that Muscovites didn't show any interest this year (at least those you communicated with) - and my weak attempt was more of a way to clear my conscience that a hypothetical alternative to St. Petersburg existed - but the active part of the audience made its decision.
