From the site: Issuu - You Publish
Issuu is the place for quality publications: Magazines, catalogs, documents, and stuff you'd normally find on print. It's the place where you become the publisher: Upload a document, it's fast, easy, and totally free. Find and comment on thousands of great publications. Join a living library, where anyone finds publications about anything and share them with friends.

After the holidays, I am going to give this a try for some of the nonprofits with which I work. One can also build a library of bookmarked publications on the site, which sounds pretty interesting as well. The testimonials are compelling.

Mashable - all that's new on the web

I love this site. Mashable provides insight into this moment's Zeitgeist for people who cannot spell zeitgeist, like me. Lots of articles about Twitter, iphones, Facebook, social networking, online marketing, startups, which companies offer good internships, and more. The stories are in plain English, with limited geek speak. They're thought-provoking, useful, and interesting - targeted to twenty-somethings, but that is part of the ....errrr....zeitgeist.

The Wayback Machine - Website, Music, Book Archives

From their site:
The Internet Archive is a 501(c)(3) non-profit that was founded to build an Internet library, with the purpose of offering permanent access for researchers, historians, and scholars to historical collections that exist in digital format. Founded in 1996 and located in the Presidio of San Francisco, the Archive has been receiving data donations from Alexa Internet and others. In late 1999, the organization started to grow to include more well-rounded collections. Now the Internet Archive includes texts, audio, moving images, and software as well as archived web pages in our collections.
