This article provides an introduction to the use of altmetrics as a tool to assess research impact. In particular, it looks at the evidence behind claims that altmetrics allow the impact of research to be measured in days rather than years. Low correlations between altmetrics and article citations make it doubtful that altmetrics can reliably predict future citations. In addition, there are good reasons to qualify statements that altmetrics measure the wider impact of research on society. Librarians should be careful not to overstate the value of altmetrics when recommending their use as a complement to more traditional measures of research quality.

Truthy is a research project that helps you understand how memes spread online. We collect tweets from Twitter and analyze them. With our statistics, images, movies, and interactive data, you can explore these dynamic networks.
Our first application was the study of astroturf campaigns in elections. Currently, we're extending our focus to several themes. Browse the collection on the Memes page. Check out the Movie tool to browse and create animations of meme networks.
schirri wie üblich --- Das Jahr 2010 könnte das Jahr sein, in dem der immer blasser gewordene Begriff „virtual reality“, der Übergangsbegriff des letzten Jahrzehnts, endgültig verlöschen wird. Die Brücke zwischen virtueller und wirklicher Wirklichkeit bricht gerade hinter uns zusammen, kaum dass wir den ersten Fußtritt ins neue Jahr gesetzt haben.
In this post from the blog "The Innovation Diaries", the author tries to categorize people's tweets into a hierarchy resembling Abraham Maslow's Hierarchy of Needs for human beings. Each category is well explained and then illustrated by a few examples.
