New version available (delta edition)

I made a new version available (delta edition, April 2010). It has the same content as the previous edition of Homo Competens - Let's talk about competent people in the network age, but with corrected spelling and more images like the 'competent people in 10 pictures' as a summary and wordle clouds for chapter summaries. It's now 226 pages. The price is about the same, it's a few cents up because of the extra pages.
