There is a technological fix for everything.
While running down the blogroll (something I don’t do as often as I should these days), I hit The Armed Citizen, who you may remember is having issues with the bottom-dwelling scum that is Righthaven LLC. In their latest thoughts on the subject, they note that there is a useful Firefox add-on along with a list by Claton Cramer of sites owned by those who are enabling the afore-mentioned bottom-dwellers.
So in addition to being much more careful about quoting from legacy media sites these days (I’ve always been careful; part of my job is understanding copyright issues, but extra care can’t hurt), can can now be somewhat certain that I won’t stumble into a nest of vipers accidentally.
