The concept is very simple.
One URL/URI points to a series of resources which have preselected by someone else. There usually arranged in someway, to either tell a story or illustrate a point
Bit.ly for example implemented bundles back in November.
We are thrilled to announce the launch of bit.ly bundles, a new way of sharing multiple links with a single bit.ly short URL.
You can start bundling links right away! Just head over to bit.ly, shorten some links and then hit the “Bundle” button.
Its a good idea but I’d like to see some standard applied to bundles. For example it would be great if Xpointer could parse bundled links. It would be possible for browsers to support a small subset of Xinclude to give a standards approach to bundled links or heck take the XLink support in Firefox and shift it towards the purpose of bundled links.
