I've done this in Instapaper. I have many thousands of articles (thanks to the instaright Firefox extension) going back years. Clearly, this is what Clay Shirky says is a filter problem, not a problem of too much information. I no longer horde in instapaper like I used to but I would like to at least be able to be able to export what I have since I started using it and even transfer the FULL archive to pocket. Probably doesn't apply to many, but: "If you have more than 2,000 articles, only the most recent 2,000 will be included. " I not only bought Instapaper, but I've been a paid subscriber since the beginning (so I can search my archive for potential research) and it would be nice to download a full archive, but nope, I can't.
