I envision my blog becoming a sort of centralized information-store for me, although I've not quite figured out how I'm going to handle sensitive information, such as addresses, phone numbers, etc. There are three approaches I've thought about: (1) use a PHP password-protection scheme to protect certain pages, (2) encrypt the data (but that sort of defeats ease of access), and (3) obfuscate the data in some simple way that I can mentally decode it on the fly -- I dunno, transpose digits in phone numbers or shift them all by 1, for instance. I'm posting this here for feedback, because the community always proves fruitful when you're wanting to do something without reinventing the wheel.
I suppose the obvious answer is: memorize the most critical data, or keep it on my person in a passworded PIM device. I'm open to people shooting down this idea of putting semi-sensitive stuff on my blog in a semi-protected format. Obviously, I'm not going to put any seriously sensitive stuff up, like financial info (credit card # anyone?)
