you can try and hold on to this 'light anonymity' as long as you want, but i feel the longer we all spend in the public fediverse, the easier it will be to piece together our content->id by fingerprinting... should someone decide they really want to do that.
ive kind of taken a more public approach...no, im not blathering my personal info about.. but i try not to say or do anything i wouldnt say or do to that person in public on the street in front of my house.
