It is true that there are sometimes interesting bits of information and discussion in the article comments, but the good stuff to reading time and effort ratio is much lower (specially because you can't just the "Sort By: Top" function to get the most upvoted replies). Considering the high time investment nature that is already inherent in the sequences, I think the commentless versions are optimal for most readers.

Maybe an editor collecting the sequences could select and include particularly enlightening comments, though.
