Darren Barefoot posted some useful points on improving your weblog, if you have one (or writing one well, if you're just starting). The ensuing conversation in his comments has some good back-and-forth as well.
I like: "Don't confuse passion with complaining. [...] If you're going to complain a lot, make sure you're very amusing doing so."
Also, if you're a woman with long hair and are considering cutting it short, go read the post from Peechie that Darren links to—it gives you a decent lowdown on how to go about it.
If you're a man with long hair and you've really gotten used to the length, the article might help you too, but men are generally a lot less stressed about lopping off big hunks of hair than women are. At least it seems that way, if the participants on "What Not to Wear" are any indication.
