Bloglines worked well. I subscribed to : librarian.net , Library Stuff Resource Shelf , and The Shifted Librarian . I'm looking forward to the aggragating function and the updates.

There are some interesting google products. I have found google scholar to be useful in the past and enjoyed google earth. Google books seems a bit deceptive as they only offer limited previews/information when you might think you are going to access full text free.

Facebook was an interesting exercise. Making contact with friends one hasn't seen in years is a wonderful use for it not to mention highlighting upcoming events for friends

For the Wikipedia element I went to the entry on the writer Garry Wills, and was surprised that the entry was as short as it is given that he has written over 40 books. As his newest book, 'Bomb Power' , has just arrived I thought I would check the accuracy of the ISBN number and sure enough it was wrong - and so I fixed (edited) it - a "minor" edit.
The entry on Wikipedia itself was very good, especially the section on "Using Wikipedia as a Research Tool", and " Strengths, Weaknesses, and Article quality in Wikipedia". This should be mandatory reading for anyone relying on Wikipedia for information.

Our Calgary Public Library Favorites on Delicious is an excellent collection of reference tools. As a group it is well managed as only relevant, up-to-date and easy to use materials are provided. Being able to select a particular tag and having all others with that tag appear is helpful as is the listing of related tags.
