To run the experiment, I am going to be drawing a few thousand links at random from the entire pool of Pinboard bookmarks. This will include private bookmarks, which make up about half the Pinboard collection. You chose to include everyone's private bookmarks in your research without asking their consent? What? I will publish some aggregate information about what I find, and use it to seek glory, and persuade people…
Why would I need consent to study the global link rot rate? Publishing it reveals no information about users, either individually or in the aggregate. I've made an effort to let anyone who wants to opt out of the research, because I know people can have strong feelings about privacy. I agree with you that publishing an 'anonymized' dataset would be a violation of privacy guarantees. I wouldn't even do it for public b…
I didn't get an email saying "There's a chance I might select your private bookmarks and examine them." A blog post doesn't count when you're messing with people's private data. Certainly it should be opt-in, and not opt-out?
You're doing this for a noble purpose, but for what it's worth, this is the first time my trust in you has ever felt violated.
People have entrusted you with years worth of private data, and you just asked, "Why should I ask permission to study their private links?"

Isn't that the opposite of privacy?
