Just found Tweetcloud via Tim Wright known as moongolfer on twitter - thanks Tim. Its an application that turns your tweets into an idea cloud going back a day, week, quarter, 6 months, year. And at 3 levels of resolution. Very very simple. Now as long as you can set up a twitter account or a list then it would seem to me that this is a very easy way to be able to monitor the keywords that it generates. Or you could set up twitter accounts for people for a particular project and ask them to use it. Then use tweetcloud to do the first pass on the headlines. Is anybody aware of other tools like ideaclouds that could be used in this way. Apparently the developer has done the same thing for Facebook. The graphic is my first as @johngriffiths7covering a year at medium resolution - which I don't find particularly illuminating - but that probably demonstrates that eclectic posting strategies don't tell you very much!!
