I'm confused. The article says that it's important that I do this, because my "data exhaust" is going to be the future currency of the web. In exactly what way? They never explain how I'm supposed to use this currency to benefit from anything. I can only assume they mean that it's someone else's currency that they can use for their benefit, which I couldn't care less about. Also, I already migrated my Delicious data -- to pinboard.in -- where the emphasis is on anti-social bookmarking. I just want to have a great way to archive and organize my bookmarks and access them on the most devices with the least difficulty in doing so and maybe have a few great features like saving cached copies of the web pages I bookmarked and doing fulltext search of the entire contents of the pages I've bookmarked. I couldn't really care less about my bookmarks being used for everyone else's benefit.
