Apture released an updated version in May 2009. Main improvements are
* new interface
* smarter suggestions to your search terms
* much faster interface with a drag and drop menu
* quick browse interface is faster
* better visual effects (it's prettier)
But a big change and interesting change is the ability to connect multiple pieces of content. So you can now connect one Apture link to multiple pieces of content - e.g. YouTube or Wikipedia or Twitter.
This layering of embedded content is a great addition - it means I can offer readers several different ways of getting additional information - e.g. video plus text.
Apture are always willing to listen to users, so if you try it out and have an idea for an improvment, you can always tweet at the Apture CEO - @tristanharris.
