Something I've noticed in my stats, having posted the odd article or two on basic html/css, is the number of searches which land people here, asking for really basic advice. How to apply a background image, what are the "proper" sizes for headings (any bleedin' size you like; so long as it's contained in heading-tags, and looks like a heading), even a few asking how to create the document in the first place. Some of them, judging by the phrasing, are getting a little desperate. Phrases like "for dummies" and "jargon-free" appear now and again. I sympathise.
One of the drawbacks of using the intertubes as a learning tool is having to sort out, without aid from a teacher, the dross from the good stuff, without even, to begin with, any knowledge of the correct terms to search for. Google for the solution to some problem or other to do with browser-incompatibility for instance, and you're more likely to find outdated solutions for similar problems affecting a now-outdated version of Internet Explorer (just for instance, but IE does throw up more than its fair share of those problems) back in 2007, than you are to find your needed solution.
And if you're a newbie, and don't even know the precise terms you should be looking for? You find yourself staring at an internet message board full of people talking about methods and terms—that you were thinking yourself clever for having worked out just the day before—being "deprecated" or just plain wrong, posting snippets of code that may or may not be good, but you wouldn't know how to apply them if they are, and, all-in-all, seemingly assuming a huge amount of basic knowledge on the part of their readers. Oh, and the ubiquitous car-park-attendant type, who always shows up to tell the originator of the thread that "This question was answered on this thread [insert plain-text url here] way back in 1996. Why the hell didn't you do a search before wasting our time?"
