Trailfire Groups - Trailfire is a way to annotate the web and create a hyperlink trail…they have now added a group feature (your trail is limited to a private or public group), wiki trails (communal editing trails), and a contacts network [via Mashable]
Snap Shots - Snap Preview Anywhere has been extended to more specific displays; a wikipedia or Amazon link will display that content excerpt instead of just a preview image of the website; a media URL will display a photo slideshow, play a video or audio clip, see the gallery.

deliciousTags2OPML - enter your del.icio.us username and ask to show tags that have a certain number of bookmarks and above. It generates an OPML code, I had to copy it in notepad and save it as test.txt.xml. Then I uploaded it to Grazr to host the file…then simply graze the feed content of your del.icio.us tags.
