The web is filled with atrocious copy.
In fact, I sometimes find myself muttering, “I see illiterate people…” (apologies to M. Night Shyamalan).
So what's the problem? Why is there so much bad copy? I think the answer is rather simple. It's contained in some advice Stephen King offers in his book, On Writing. King says that the two keys to being a good writer are, “read a lot, and write a lot.”
If you say that you just don't have the time to read very much, you're kidding yourself. You're not serious about your craft. Even more so if your excuse is you don't have time to write very much.
If you want to improve your skill as a writer, you have your marching orders: read more, and write more.
