Its a social media mentions (activity?) tool that counts the number of tweets, likes and +1′s of the home page of 3 sites that you put in to the tool.
You can find the tool here
One nice thing about the tool is that if you don’t like the alignment of the circles that the tool produces, simply MOVE THEM to where you like – you will see what I mean
The tool also produces a bar chart that shows a breakdown of tweets, likes and +1′s to each site.
Hope it is of interest to social media nuts around the world.
*at the time of writing, this tool looks very bare. In a short while I will change the design of the tool to match the others on this site.
