How would this work?
Automagically of course :) You would attach one or more RSS feed for a specific delicious tag to a bricabox and content would automatically be added to the bricabox when it gets bookmarked under that tag. A lot of the content in a bricabox would probably already be bookmarked by users.
It seems like Bricabox is about attaching meaning and thus structure around common datasets not necessarily sourcing the datasets. Delicious is the defacto standard for sourcing common dataset through links (which includes a title and description). I use delicious extensively and I can see how it would be very helpful for me to add structure to a subset of my bookmarks and share that with a group. e.g. I bookmark all of my potential competitors as beyoucompetition in delicious. I would love to import all of these into a bricabox and have my team add notes and rate/rank each of the competitors. I can imagine that there are a ton more usecases that would work with existing delicious bookmarks.
You could take this to the next level and add parsing for simple but very useful data elements that would be purposefully added to the delicious descriptions. An immediate example is adding the geocode or address for a link that describes a location. Obviously the more automated this is, the better.
Definitely. delicious would just be a standard template for RSS that the user could select.
