iA have created a visualization of the 140 most followed ‘twitter-ers’ (size of dot=followers) and their influence (algorithmic? size of grey bubble=impact) by social spheres (in pie-slices around the circle) and over time (radially from the centre).

“Here it is, our next Web Trend Map. No Metro lines, no URLS. This time, it’s the 140 most influential people on twitter, sorted by #name #handle #category #influence #activity. Plus: When they started tweeting and what they first said. It took quite some time until we had it in the shape we envisioned. Since there is a lot of data we processed to get it here, we’d like to ask you to give it a final check. Tell us if you find any errors, before we send the file to the printer.”
