Well... what do you intend to do? To minimize any chance of being doxxed, use only throwaway information (name, email, etc...) and use Tails whenever accessing or writing to your blog:
https://tails.boum.org/I would also recommend subtly revealing "fake" personal information in some of your posts to further confuse any attackers. If you actually live in Florida, say that you enjoy the beaches of California or something.
Regardless, any attacker dedicated enough will find out who you are, so the best thing to do is to not do anything blatantly stupid to begin with.
