I'm no longer even going to try to comment on any blog that uses Discus or Facebook to manage their commenting function. My comments on one site do not need to be viewed by the other participants at some other, unrelated website I might visit a year from now. And my Facebook friends are already overwhelmed with alerts from my posts, they don't need all this too.
And frankly, me and the NSA are the only people who need to have a Collected Works of my comments around the interwebs.
So I'll still read, and maybe even share, posts on such blogs. But that is why you don't hear a peep from me.
And thank you to those folks that use a commenting software that lets me be myself without pooling my information with every other site I visit.
