.. the title of this post came from a comment on Metafilter discussing Digg. But it applies to a much wider range of things currently happening online in newspaper content, paywalls, microtransactions, apps etc. I haven't seen a more succinct way of describing the trade-off for not paying for content online. The two basic models are either you buy the content, or someone buys (or leases)  you, your attention and your data.

PS. Of course, sometimes you pay for it and are still the product as well..
