Mike Linksvayer *himself* is to blame for the non-liquidity of his Wikipedia prediction markets.

Mike Linksvayer:

Prior to the Wikipedia community vote on adopting CC BY-SA it crossed my mind to set up several play money prediction market contracts concerning the above outcomes conditioned on Wikipedia adopting CC BY-SA by August 1, 2009, for which I did set up a contract. It is just as well that I didn’t — or rather if I had, I would have had to heavily promote all of the contracts in order to stimulate any play trading — the basic adoption contract at this point hasn’t budged from 56% since the vote results were announced, which means nobody is paying attention to the contract on Hubdub.

Blame yourself, Mike. I blogged 10 times about the concept of &#8220-X group&#8221- &#8212-the symbiosis between a set of prediction markets and a set of bloggers.


Predictify gets the X Groups concept right.

#1. X Groups

Predictify is unveiling a two-way interaction between their prediction platform and the blogs out there.

  1. FROM THE BLOGS TO PREDICTIFY: Number one, there is now a customized prediction widget that bloggers can embed in their blog posts so that their readers can vote within each blog post &#8212-without leaving the blog.
  2. FROM PREDICTIFY TO THE BLOGS: Number two, there is now a trackback widget that bloggers can embed in their blog posts so that the blog readers can click and be connected to relevant questions on Predictify, based on the content in that particular post. As soon as one of the blog readers clicks a highlighted question, that question will have (on the Predicitif webpage) a trackback to the blog post &#8212-theoretically pulling traffic from Predictify to that blog. The first problem with this second feature is that only the most popular trackback will be published on the particular Predictify webpage, as I understand it. I don&#8217-t see how bloggers could be interested if there is no guarantee that their trackback will actually appear. The second problem is that we don&#8217-t know whether Predictify abides by the &#8220-do follow&#8221- policy, which is a way for a website to injects Google PageRank juice to the website it links to. (The opposite policy is called &#8220-no follow&#8221-.) Only the &#8220-do follow&#8221- approach would get bloggers interested in that scheme. Predictify should clarify that.
  3. UPDATE: All the trackbacks will appear. They will be sorted by popularity. And, yes, Predictify has a &#8220-do follow&#8221- policy. :-D

#2: Social Networking

I&#8217-m told that Predictify will soon unveil a FaceBook application. We will see whether it&#8217-s Predictify working on FaceBook or Predictify woking with FaceBook. See the difference? (YooPick works on FaceBook, not with FaceBook.)

My plea to Yahoo! research scientist David Pennock

My Dear Honorable Doctor David Pennock,

Please, give us more choices. We want to be able to choose between:

real-world outcomes and Yahoo! search outcomes


– play money (Yootles) and real money (in the U.K., thru a BetFair patnership).

WE WANT FREEDOM, DOCTOR PENNOCK. DON&#8217-T IMPOSE YOUR PREFERENCES ON US. Ever heard of the Statue of Liberty that the French gave to your people, man??

Addendum: I almost forgot. And we want a high level of interactivity between blogs and prediction markets. Plus, we want imaginary prediction markets. Hurry up- we&#8217-re waiting.
