I have been a big fan of social bookmarking and my preferred tool for social bookmarking has been Delicious. With the initial rumor that Yahoo will be discontinuing it and now the news they may be selling it, I imported my bookmarks to Diigo. It was a very easy process and retained all of my tags. This is great because I often share these tags on my blog, Twitter, e-mail and even in the classroom, so seeing them preserved was very important to me. Here are some of the tags I share the most, which are now available in Diigo:
I also added a Diigo widget to this bog. So, if you are a Diigo user you can bookmark my posts using the icon in the right column. I have also inserted a working example below.
