I just don’t like fighting with people’s writing. I don’t like having to slow down and read sentences twice in order to understand them, when a simple punctuation mark could have made the whole process much easier. I don’t like wondering how a writer expects me to take him or her seriously if they haven’t learned to spell simple words like “definitely” and “ridiculous” (two of the most oft-misspelled words I’ve ever seen on the Web). Just about everything has a spellchecker, so what gives? I’m not judging anyone’s intelligence — just their willingness to communicate their ideas in a way that doesn’t seem messy and unfinished.

As I said, I may be doing myself a disservice, because I tend to blow someone off after about the third or fourth misspelling or run-on sentence. But ideas tend to trickle down in the blogosphere. Good ideas (bad ones, too) are repeated and expanded upon, sometimes by bloggers more adept at the written word.

“If they can’t spell worth a damn, why I am trusting their knowledge on this topic?”

I feel this way about the entire Internet. I’m sure it’s to my detriment in some regard, because I’ll write off a blogger’s entire body of work, but seriously: If you systematically misspell words or use lousy grammar, that means you probably don’t read very much, or you don’t pay attention when you do read. And if you’re not a reader, what the hell are you basing your thoughts on?

And most importantly you need to know the subject you are talking about

Another thing is layout. Your post has nice section headers, lists when necessary, etc. Too many tutorials seem to forgo this crucial step. It makes it much easier to look back at them and find the specific information you’re looking for.
