There's a middle ground, certainly.

I maintain a site (for a loose definition of "maintain", I suppose) called http://fuckingblocksyntax.com. It's wildly popular in the Objective-C development community, due in no small part to the memorable domain name. But the site itself doesn't contain profanity or over-the-top machismo bravado, and there's a safe-for-work mirror URL at http://goshdarnblocksyntax.com.

A little profanity goes a long way.
