I was  reading the rejection of imechanica from NSF

A "Supreme Court" for peer review of papers and proposals

And these sentences came to my mind.....

Important update (July 6, 2008)

• Wikipedia on peer review --- an excellent article, an example of wikipedia quality, and interesting anyway!

Dear fellow iMechanica users,

Many of you have experienced unstable access to iMechanica recently.  To our best knowledge, such unstable performance can be related to the fast-growing user volume of iMechanica. We have been working with Lesley Lam at OIT of Harvard School of Engineering and Applied Sciences to cure such growing pains of iMechanica.  We apologize for any inconvenience due to unstable access to iMechanica, and appreciate your understanding while we're working on this issue.  The support from all of you has been vital to iMechanica since day one and will continue to be so for the years to come.

The number of registered users of iMechanica reaches 7000 on 11 May 2008. So far, our fellow iMechanicians have contributed 3172 posts and 7425 comments.  The evolving statistics of iMechanica
(see the latest updates here and here) shows a steady growth with no sign of slowing down. 

Check out the earlier milestones of iMechanica when the number of registered users reached:

6000

I think it would be useful to collect a list of most useful sites, to start with iMechanica-look-alike.  Not exactly similar but a good site for CFD is http://www.cfd-online.com/.  This incidentally suggests us some "ways" to improve iMechanica.  (see my other blog PROPOSAL for iMechanica http://imechanica.org/node/2996)

Dear fellow iMechanicians:

After some technical problems over the past weekend, iMechanica is now back on full service. We apologize for any inconvenience this may cause and thank for your patience.

We are particularly grateful to Ms. Lesley Lam in OIT of Harvard School of Engineering and Applied Sciences for her prompt fix of the problem.

Hello imechanica users: I launch a few ideas. Can we improve imechanica stealing ideas from successful web systems like google, amazon, wikipedia, myspace, youtube? Taking the best of the various worlds to improve our imechanica?

Integrating Content Detail and Critical Reasoning by Peer Review

Information in Imechanica is a little dispersed it is good in its present form but is it possible to categorization of information more?

On 6 June 2007, about 50 mechanicians attended a special session at the McMat 2007, "iMechanica.org get together". The attendees of this special session came from various job sectors, such as academia, industry as well as government agencies. The session was chaired by K. Ravi-Chander and Rui Huang, who also served in the organizing committee of McMat 2007.

Abstract: Web 2.0 refers to a collection of second generation web services, such as blogs, social bookmarking, wikis, podcasts, and Really Simple Syndicates (RSS) feeds.  While the first generation web (Web 1.0) is about linking information available online, Web 2.0 emphasizes online collaboration and sharing among people.  These new web services bring up new opportunities to innovate how we conduct research and education. We report the preliminary explorations of engineering education exploiting Web 2.0 services, through iMechanica (http://imechanica.org). 

Reading the article, future role of iMechanica (http://imechanica.org/node/908) posted by Teng (http://imechanica.org/user/10), I am thinking that iMechanica may replace mechanical seminars, lectures conducted by invited mechanicians, in the future.

Academic seminars have several functions: first, to exchange information; second, to build up connections.

1. Introductory

Recently, there has been some active discussion on topics like:
-- Open-source textbooks
-- Comparing lecture notes
-- Unification of mechanics
-- Wikipedia and Citizendium

Since iMechanica went official on 9 September 2006, its growth has always been accelerating. As of 22 February 2007, the total number of hits on iMechanica reaches 1,000,000+, iMechanica has 1252 registered users, 908 posts and 1308 comments.
