[Confusion]

As tristan_juricek commented elsewhere:

Uh, using language like "bottom-feeder RDBMS" and saying that an engineering team is using it "horribly incorrectly on clearly comically deficient hardware" makes this article highly biased, and trollish. It's pretty clear that this guy things Digg is a bunch of idiot engineers - I mean, why else allude to "rudimentary comp. sci. knowledge"? These articles might have a central point, but when it's surrounded by a bunch of opinion, it like watching TV news (e.g., Fox News). The real information gets drowned out.

That's a pretty good reason to flag a story. The entire argument is based on the premise that others are idiots: hubris of which we are often guilty. After you've been in the trenches for a while, you should realize that there is usually a pretty reasonable explanation for seemingly stupid problems.
