I'm all for adopting an informal tone. I'm even perfectly okay with using slang and a bit of profanity, if necessary. But here's where I draw the line: Informal writing is not the same as sloppy writing. Casual writing is not the same as careless writing. At the risk of offending anyone, I'm here to tell you that far too much of what I read online falls somewhere between garbage and crap. Once my crap detector goes off, I'm gone—off your blog, off your site and out of your world.
