DELICIOUS

http://www.delicious.com/

Delicious (formerly del.icio.us) is a social bookmarking web service  for storing, sharing, and discovering web bookmarks. The site was founded by Josha Schachter in 2003 and acquired by Yahoo! in 2005. By the end of 2008, the service claimed more than 5.3 million users and

180 million unique bookmarked URLs. It is headquartered in Sunnyval, California.

Delicious uses a non-hierarchical classification system in which users can tag each of their bookmarks with freely chosen index terms (generating a kind offolksonomy). A combined view of everyone's bookmarks with a given tag is available; for instance, the URL http://delicious.com/tag/wiki displays all of the most recent links tagged "wiki". Its collective nature makes it possible to view bookmarks added by other users.

SlideShare is a Web 2.0 based slide hosting service. Users can upload files privately or publicly in the following file formats: PowerPoint, PDF, Keynote or OpenOffice presentations. Slide decks can then be viewed on the site itself, on hand held devices or embedded on other sites.

The website was originally meant to be used for businesses to share slides among employees more easily, but it has since expanded to also become a host of a large number of slides which are uploaded merely to entertain.Although the website is primarily a slide hosting service, it also supports documents, PDFs, videos and webinars. SlideShare also provides users the ability to rate, comment on, and share the uploaded content. The current list of SlideShare's investors includes Venrock, David Siminoff and Dev Khare. 

GLOGSTER

http://www.glogster.com/

Glogster is a social network that allows users to create free interactive posters, or glogs. A glog, short for graphical blog, is an interactive multimedia image. It looks like a poster, but readers can interact with the content. Glogster was founded in 2007. Currently this social network has over one million registered users. The majority of the Glogster community are teenangers. 

Glogster provides an environment to design interactive posters. The user inserts text, images, photos, audio (MP3), videos, special effects and other elements into their glogs to generate a multimedia online creation. Glogster is based on Adobe Flash elements. Posters can be shared with other users on the site, embedded in external wikis or blogs, and shared via many social networks such as Facebook and Twitter. Glogs can also be exported and saved to computer-compatible formats.
