Both "substance" and "a lot" are entirely a matter of personal taste in this instance, I guess. I don't consider a word "x" appearing 0.04482294935006723442402510085% of the time in a post to be "a lot", but I recognize the existence of people who believe more than 0 of anything is a lot.
For the substance, well, there's a lot of words there, but of course I've read posts with 40 words and posts with 11,000 words that both conveyed the same small amount of substance. I do think the link has a non-zero not-insignificant amount to add (or why bother sharing as a child of another link-sharing comment) especially if you include the links from that link; I think it has at least as much substance as the actual submission here. (And look, the author himself has even posted here, splendid. If you think his light-weight comments here have substance, make sure you give him an upvote.)
