Honestly, this data should be free, and available to researchers who work on social tagging.
You should contribute your bookmarks to a public data set. http://bulk.archive.org has offered to host such data sets.
Someone should build a webservice that allows you to easily share your delicious tags. If no one steps up, you can simply email me your export (turian at gmail), and I'll package up whatever I receive.
I never really fell in love with delicious (partly because I could never remember where to put the dots). I have, however, found a good bit of use out of Historious lately.
StavrosK is quick to mention it (he did in another Historious thread already), but I figured I'd give some endorsement for him. I like it (and I paid for a year).
The full-text search of the bookmarks (at the time you bookmarked them) is the key feature - it really does come in handy. It's also nice that it caches the text of those links as well.
Anyone worked out how to import delicious to Firefox yet, with tags and all?
If you import the HTML they give you it doesn't import tags so I have a huge bunch of untagged bookmarks :(

Here is a delicious data set, for those who are interested: http://arvindn.livejournal.com/116137.html
I have some other social tagging datasets in my file. Let me know if you'd like me to dig them up.
