LJ are doing the link re-writing thing again. As this post makes clear, the reason it is bad (even if you don't care about money, like I don't) is essentially because a third party company will get info about what links to external websites you are clicking, if you are clicking on them when they've been posted by people who haven't opted out of this scheme. I have, and absent LJ being total arseholes about it and ingnoring the opt-out (at which point, I will be shutting up shop on LJ) links clicked from my journal should always be safe. Do me a favour, and leave a comment if you've similarly opted out, so I can try and track whose links I am happy to click?
