I'm particularly fond of the quote "lead, follow, or get the hell out of the way", which is a bit harsh in this case because a lot of your advice is good. It could be framed in a more constructive way, though - there's some Comic Book Guy tone there in your comment.
My intended tone was not "don't try", but "try harder".
I've listed at least 5 ways to improve/normalize the testing, as well as linking to a document that does a pretty good job of explaining statistics (particularly, how programmers do a bad job of statistics; baselines for benchmarks; etc).
"At least he's out there trying" -- with this not-so-great benchmarking, the author has just effectively SHITTED on 2/3 companies that have gone to great lengths to build amazing infrastructure AND managed to spread his FUD around the web, to the point where it reached the HN front page -- and you want credit for trying?
Get the hell out of the way.
It's probably also true that your tone is more abrasive than it needs to be.
"At least we're doing something!" is a silly defense.
EDIT: I should probably mention I work at Rackspace, and thus everything I say on this subject should be taken with appropriate grains of sand :)
Many argue that the AWS ecosystem (25 services at last count) and the extensive featureset of AWS outweigh the bare bones "fast" metrics of other providers.
I think like the poster above is mentioning...there is generally more to it than a simple metric or two sampled a few times from a single endpoint. But I guess it all lies on ones definition of what they consider valuable...
