I started checking out some of the delicious alternatives mentioned on the searchengineland.com site. Here are some initial impressions of one of them: Diigo.
Digo can do what Delicious does, and more. It is easy to import your bookmarks from Delicious.
Using the Firefox plug-in, you can add notes and highlight sections of the pages you bookmark . You can save a cached version for archival purposes, and include a graphic image of the page.
It integrates well with Firefox. You can preview a bookmark right from your “Library” by clicking the “preview” button. I think it’s pretty slick, but way more than you need if you just want to save bookmarks.
On the downside: 1) Free accounts are limited and come with advertising 2) The current holiday color scheme is annoying (presumably this is temporary) 3) No blackberry app. 4) No way (that I can see) to backup or transfer your data in case you need to move it elsewhere.
