Would be nice to add Delicious widget (can see example at http://www.jmcpherson.org) with parameters like which tags or which tab bundles to show for a certain person

Apart from web widgets that Delicious already offers (see link above for example), could also make your own based on the feeds reader I guess.

For example for user birbilis (http://www.delicious.com/birbilis), for the tag Robotics (http://www.delicious.com/birbilis/Robotics), the feed is:

http://feeds.delicious.com/v2/rss/birbilis/robotics?count=15

(set to feed latest 15 items)

and for Robotics+Microsoft the page is:

http://delicious.com/birbilis/Robotics+microsoft

and the feed is:

http://feeds.delicious.com/v2/rss/birbilis/Robotics+microsoft?count=15

So params the component would need would be USER (could be left empty to search all users) and a TAGS list (which the widget would concatenate with +) and a COUNT param too

NOTE: if user tag is left empty, the url should be something like:

http://feeds.delicious.com/v2/rss/tag/Robotics?count=15

(and not http://feeds.delicious.com/v2/rss/Robotics?count=15 because that one shows the tags of the user called "Robotics" - there happens to be one btw - this just bit me and that's how I noticed the correct URL is with "/tag/" if one searches the top level [luckily Delicious guys thought about this possibility])

Make sure to also checkout their cool tools at:

esp. the Tagometer, Linkrolls and Tagrolls (=tag cloud)



indeed, depends though who your users are and if you want to allow them to add custom HTML to your portal
