What have I been up to at the start of 2011. Lots of swimming and working on WordCampNZ 2011. This mention map looks to be interactive and probably updates in real time.
Hover over the map to explore connections. Enter your twitter id to view your own map.
Note: the original flash version from http://apps.asterisq.com/mentionmap died some time back so have just added a screenshot in April 2012 to fill the space. Very interesting to see that some people hotpspots are still hot even 18 months later.
Not sure if this link will work Mention map – dialogcrm you may need to login to your twitter account from mentionmap.
