Friendfeed is typical of most lifestreaming services in which updates from different sources will be listed one by one in a list, one on top of another.
However a few lifestreaming services are a different breed of lifestreaming service, what Lifestreaming blog calls "time-lined based"
It is fully interactive, you can embed it in any webpage and users can zoom in, zoom out to see more details etc.
All in all, it is a lot more visually appealing then the average lifestreaming service, which shows updates one after another in a horziontal list.
Another two other modes are offered, one is "Flipbook view" (see below)
Just flip through each update, like flipping through pages of a book.
Perhaps the most interesting one is the Map view.
Map view is a bit difficult to explain. Basically in one of the blog posts one librarian reviewed a fiction book set in Italy, as a result it appears on the map in Italy, and if you click on it, it will show the corresponding post. This is a simple example of what they call geo-tagging (roughly speaking this involves tagging an item such as blog post, image etc with the geographical location associated with it).
Possibly, the images don't do full justice to the concept, go to http://www.dipity.com/Nuslibraries/ to play with it.
You can also embed it as a widget on any webpage, blog or even Facebook.
I think time-line based lifestreaming is a very interesting way of providing a visual record of library activities over a period of time. There are some things to iron out though, like ensuring that your blog post about Library event X, and the photos on the same event X posted to Flickr account should appear on the same day etc.
