I have a Slideshare account that I use to publish slides of presentations I’ve held (if it’s okay to publish them, which is the case only very occasionally). Sometimes Slideshare sends me e-mail news that I more often trash than skim.

Recently, I was pointed to Typealyzer, a tool for analysing blog types or, actually, the personality types of the people behind the blog. The information is visualised in a spider chart with eight personality dimensions.
Typealyzer is the doing of Mattias Ostmar and Jon Kågström, the former being a (self-described) media and communication geek and Communication Analyst at Sweden-based PRfekt. Mattias specialises in psychological text analysis. Besides Typealyzer he has several other projects in that field. His website/blog is http://www.mattiasostmar.net and his Typealyzer profile looks like this:
Today’s Economist‘s Daily Chart features a diagram of scientific citations per country: The diagram has two parts: a donut chart showing the proportion of citations per country for 1999-2003 and one for 2004-2008.
