Resisting the urge to start a blog

Part of me wants to do it so bad. Just to post meaningless little navel-gazing ramblings and convince myself that I have something to say. Not a diary-type blog but one of those anonymous "cultural critique" ones that everyone thinks they could write. Truthfully, it would be fun to just talk into the void in a way that's a little more structured than some place like this and it would be a good exercise. But I can't shake the feeling that it would be a waste of time, turn me into a narcissist, and be a little embarrassing, especially if anyone IRL found out about it. Anyone else have experiences blogging? 🎲
