Renowned US PR professional and blogger, Brian Solis, has devised the “Conversation Prism”, a chart which marks all types of online interaction as well as many of the tools which perform them. Brian remains true to the essence of the online community by allowing his users to contribute – items he might have missed may be added to the Converasation Prism image on his Flickr account.
Aside from the sheer number of online tools, two things stand out for me when looking at the prism: 1) is the amount of lifestream/micorblogging related tools – these are all the rage in the US, but nowhere near as much so over here in Europe; and 2) the relatively few numbers of wiki tools, although online collaboration using wikis was expected to rival blogging as the new web interaction method of choice a couple of years ago.
