When I started out I blocked out Texas for the same reasons that you blocked out California--I'm from here, some of my family lives here, etc. etc. But, Texas is huge, and there's not just one demographic that I do well in, but many that live here. So, I unblocked Texas, and some of my best tippers/talkers have been from Texas. It's really fun to bond with someone over what's happening in the state-especially our freaking crazy ass weather-and have someone to just shoot the shit with from the state. I found blocking Texas too restrictive, and I ultimately came to grips with the fact that, eventually, someone, somewhere, will find me and what I've done on the internet--because the net is forever. If my friends find out? Okay, the ones I care about knowing already know, same with my family, and the guys I work with wouldn't give a rat's ass.
But, it comes down to you and what you want. If you want to keep California blocked, keep them blocked. But, just remember that Cali is huge, it's the 5th largest economy in the world, takes up a good chunk of the West Coast, and takes a big chunk of the west coast time-slot. I'm not trying to pressure you at all, btw, your comfort at what you're doing and who you are are paramount. I'm just bringing up points to consider.
