Digg, the social news ranking site, has been getting a lot of coverage lately. It started with Alex Bosworth's excellent Dynamics of Digg post, where he suggested there are 5 types of Digg users. Richard MacManus summarized his points nicely:
1. Readers: Alex guesstimates that "ten to twenty percent of those ever click 'digg'". I'd love to know the actual figure though.
2. Diggers: 10-20% says Alex. He also says these are the least important members of the system, because "once a link is on the front page, it makes marginal difference the number of votes next to the link."
3. Hardcore Diggers: "people who sit in the queue of submitted stories and watch for breaking news that should make its way up to the front page, or report stories as being spam or irrelevant."
4. Submitters: people who submit stories. It's highly competitive and difficult to be the first to post a successful story (one that makes the front page)
5. Publishers: "often bloggers who want to get readership for their content."
