"The irony is that most startup blogs are written and maintained by failed entrepreneurs."

In the last six months or so, I've felt the same way about a lot of the users here on HN. It's a joke amongst my friends who also read this site that we wish there was a "PROVE IT" button next to each comment... just as a way to tweak all of the people who like to talk like they've come down the mountain with stone tablets to tell us how to do things.

That's not to say that everyone here who has taken the time to offer advice and suggestions to others is full of it, of course. Yet I still think you should hesitate to take a lot of what people say with any degree of importance until you know that their background justifies it.
