Del.icio.us, the social bookmark service that we’ve used for our Shrapnel links, is getting the bullet to the head courtesy of Yahoo. If you still need a cross-browser bookmarking service, take a look at Xmarks. There’s also Diigo, which not only stores bookmarks but also lets you store the whole web page and annotate it. Both will let you import your Del.icio.us bookmarks.
Update: Several friends also pointed me to Pinboard, which bills itself as “socal bookmarking for introverts”.
