For some blog sites I agree, but here it is Philip Greenspun who shares his email, phone number and physical mailing address on his website! I've sent an email about the typo at that address.
I usually look for an email on the blog site, then on thier other/main sites, then a direct message option on twitter, then a contact in whois for that domain, then, as much as it drive me nuts that it could be corrected so easily, it's just a tipo after all, and I try to let it go.
I completely get you, and as someone who cringes at Linus Torvalds's "touch" typing style (which makes me wonder if that's where some of his overall "style" comes from), I wish there was an easy package or plugin that could be popularly applied to publishing and posting software (e.g., web browsers). It doesn't need to be mandatory, but I'm sure many people wouldn't mind the option so long as it's not open for abuse.
