At some point or another almost every blogger writes a controversial article, some bloggers do it so frequently that it doesn't generate that much press now.
Some will try to dictate rules for the blogosphere, that kinda defeats the purpose of the blog, I think that's just people trying to create the next buzzword or leave their legacy which translates into popularity and everything that comes with that, if you are a "z list" blogger like me, it probably won't make a difference if you post something that is incorrect.

Today I see this post from Sam Gentile: "Wanted: A Windows Edition for Non-Idiots"; my whole issue with that is calling regular users idiots; if I use the keyboard and command line a lot does that make me an advanced user and makes you an idiot because you don't?
Be careful when blogging, regardless of your blog popularity, you never know when it can be used against you (in a job* interview for example), I'm not going to recommend a code of conduct, all I'm saying is use common sense, respect your readers and respect everyone in general
* fixed: thanks Sam
** Sam updated his blog and changed the "non-idiots" part to "Power and Pro Users.", kudos to him for doing that. I've wanted to blog about this a long time ago, my whole point is just watch what you write on your blog (book, speech, etc), it may come back and hunt you later
