Nothing makes me more sad then when a bad article get popular. SEOmoz has an article called “5 HTML elements you probably never use (but perhaps should)” a title that would get about any article bookmarked. But it’s a very disingenuous title.
They think you should use the <q> tag for quotes though it has no support in IE. How is this helpful at all? Sure it’s sad that IE doesn’t support it but it’s hard to then tell me I should always be using that tag.
And I would argue that <acronym> and <abbr> are fairly wide used. I maybe biased since I read mostly web designer blogs but I see these all the time.
I’m coming to the point where I dread clicking on any article with top 10 this or 5 of this other thing you should use. When will the insanity stop?
