I have a devil may care attitude. I stay relatively anonymous without blatant revelation but with enough research someone could probably figure out who I am. I suspect that some family and a few others realize who I am here and follow my postings. If not, there have been some pretty amazing, coincidental, real-life, non-sequitor conversations and hints at secret knowledge of relative topics that I have over-revealed myself to here on the board. I have no definitive proof but feel that there are benign, malicious, as well as ambivalent forces that have access to my postings here and elsewhere. It doesn’t really bother me.
If you’re like me and have no real reputation to protect, nothing to lose, and very little dignity nor self-respect left, then posting without regard has a net-positive and affirmative effect. If you worry about posting and have been burnt before, then you might want to excercise some more discretion and write broadly; avoid the posts that will make you a composite figure i.e. polls, personal anecdotes, location threads, etc.
Stay amorphous and you will feel more secure. The downside is you will lose out on some vaguely satisfying interactions of personalization and intimacy. Oh, and Barracuda, here you would do well to watch out for the devils you know… they could probably do you more psychic, emotional, and general malevolent harm by osmosis than any anonymous, personal, or tracking entity, which, of course, conceivably could simultaneously be one and the same.
