Scoop.it!
Researchers at Harvard took the time to dig into our brains to figure out why 40 percent of our daily speech is centered around telling others what we think and feel. And the reason? Because it feels so good!
In a series of experiments, they compared the feeling one gets from eating food, getting money or having sex with the feeling one gets from disclosing information about oneself. The study revealed that the feeling one gets from all of the above is strikingly similar, they all give the same feel-good feeling. This explains why we tweet and update about ourselves so often. It seems that self-disclosure activates the mesolimbic dopaminergic system of the brain, which is associated with the same rewarding feeling as getting money or sex.
===> So Tweeps, now you know what to do when you have the blues: start tweeting and updating your status! <===

This is good that they are helping
Perma.cc is an upcoming web service that aims to help authors and journals create permanent archival copies of their online published content.
Way too often in fact, due to a multitude of reasons, not only content gets moved and relocated to new sites, becoming more difficult to find but in many others it is permanently deleted or lost.
To comfort your doubts that this is a true and tangible issue, you should check the work being carried out by Kendra Albert, Larry Lessig and Jonathan Zittrain, who are completing a study of link rot, available at http://papers.ssrn.com/abstract=2329161. ;
Link rot is the phenomenon by which material we link to on the distributed Web vanishes or changes beyond recognition over time.
Believe it or not half of the links in all of the Supreme Court opinions, don't work anymore.
In this context "the Harvard Library Innovation Lab has pioneered a project to unite libraries so that link rot can be mitigated. We are joined by about thirty law libraries around the world to start Perma.cc, which will allow those libraries on direction of authors and journal editors to store permanent caches of otherwise ephemeral links."
The Internet Archive has provided its powerful archiving engine to support this effort and Cloudfare its distributed CDN.
The official tagline of the upcoming site reads: "perma.cc helps authors and journals create permanent archived citations in their published work"
Here is essence what you should expect from it: "Perma.cc allows users to create citation links that will never break.
When a user creates a Perma.cc link, Perma.cc archives a copy of the referenced content, and generates a link to an unalterable hosted instance of the site.
Regardless of what may happen to the original source, if the link is later published by a journal using the Perma.cc service, the archived version will always be available through the Perma.cc link."
N.B.: While anyone will be able to go to Perma.cc and archive any web page this resource is designed for researchers, authors and journals. In this light Perma.cc downloads the material at the designated URL and provides a new URL (a “Perma.cc link”) that can then be inserted in a paper.
After the paper has been submitted to a journal, the journal staff checks that the provided Perma.cc link actually represents the cited material. If it does, the staff “vests” the link and it is forever preserved. Links that are not “vested” will be preserved for two years, at which point the author will have the option to renew the link for another two years.
My comment: Can't wait to test it. We need these type of archival tools like oxygen. It's not only important that we organize and curate what is important from the web, but it is essential that we also take care in preserving it for the longest possible time.
Free and open to all (soon).
