Compendium of the Best Approximation and Hardness Results for NP optimization problems Do you know any up-to-date wiki dedicated to NP optimization problems with their best approximation and hardness result?

Based on the feedback, it seems that it is safe to assume there is not such a resource (see the end of this question for two close options). -- added on Feb 8.

Since there is a huge body of results and problems introduced in the past two decades, existence of a dedicated wiki could be a great help for students and professionals working on subject of approximation algorithms and hardness of approximation.

I have been suggested to start a new wiki. I like the idea, but I need some feedback before starting:
Are you interested in a wiki devoted to the above subject and are you going to contribute something? What is your preferred format for this wiki (see my preferred format in comments)? Should we use a wiki farm or a wiki engine? In the latter case, what is your suggestion for a wiki engine? MediaWiki?

The two closest options that I am aware of, are:
1- "A compendium of NP optimization problems," edited by Pierluigi Crescenzi and Viggo Kann: This compendium seems to be out-of-date. I think the volume of current results cannot be managed by a few people and if we want an up-to-date list, we should have a wiki.
2- Wikipedia: This wiki is for general audience and you cannot have a short page just including problem description, and the best approximation and hardness result.
When you refer to the Crescenzi-Kann compendium, I'm not sure if you're referring to the book or the website.  The book is out of date but the authors try to keep the website continuously updated.  It would seem that the logical starting point is to approach Crescenzi and Kann with your proposal.
