I'm constantly amazed at the imagination and creativeness of the people coming up with vital web applications that I didn't know I needed until I discovered them. Firefox now has so many add-ons that really can simplify one's browsing experience, as well as add to the enjoyment.
As Rick Anderson said in his blog, and I must say that I agree with him, that I believe our patrons will expect, and have the right to expect, access to all 'emerging' technologies, digital collections of journals, books, blogs, podcasts, etc.. They are never 'emerging' for very long, but quickly become part of our patron's daily lives, especially the curious and the young.
Random thought: I would just like to make a suggestion to whoever designs library catalogues. Please add that famous Google 'did you mean' feature...
