Glogster.com is a social network which allows users to create free interactive posters, called glogs, under the motto poster yourself. A glog, short from for graphic blog, is a multimedia interactive image. Aparently, it is just a poster but users may interact with its content. Projet Glogster was founded in 2007, in the United States. Nowadays it is a social network with thousands of registered users, mainly youngsters. The user inserts text, pictures, photos, sound (MP3), videos, special effects and other elements in their glogs in order to create an online multimedia tool. Glogster is based on Flash elements, and the posters may be shared with other people, exported and saved in compatible formats or even published in a wiki or blog. Similarly to Facebook, Glogster allows you to create a profile, a network of friends and you will be able to comment your favourite glogs.
