Delicious/Diigo

I started an account with Diigo because I was under the impression (maybe falsely) that Delicious was closing down and all accounts were to be transferrred to Diigo.  Diigo works under the same bookmarking principle and since I discovered the concept, am really pleased with the site.  I don't have a laptop for work and was constantly frustrated with the lack of access to my bookmarked sites when working from home.  I am still in the process of transferring them all to Diigo and, despite of the time it is taking to complete, being able to access the information I need when I need it makes the effort worthwhile.  I like the idea of creating your own tags ensures that information retrieval is efficient and relevant to your individual way of working and thinking.  Additionally, if your computer crashes, having the bookmarks stored in the 'cloud' means they are not lost.  Great site, fabulous concept.
