The online applications and tools are fabulous and I'm looking forward to playing around with them. I love the idea that it's "out there" where you can access your info from anywhere without having to carry it around. I also like the way you have control over who can see it. I found some limitations on Googledocs but it may be MY limitations more than the program! I think ZOHO looks amazing. This is great stuff for small rural libraries that need constant contact with headq and would save lots of emailing and faxing.
I had trouble sharing my document with nswpln@gmail.com. Was a bit stumped as to how to go about that bit!

Mashups are lots of fun. They could be used for all kinds of things in the library context. I just had a go at name-badges, and I can see how easy it is to do!

Fantastic way to make training available to those of us out in the bush! Sydney is 9-10 hours drive so we never get to any of the programs up there! Great potential for library use and it may already be happening and I don't know it!

Wikianswers is an interesting site. Very diverse. Is Answer Board Librarians Wiki still happening? Great idea but how successful ws it over the long term? I do like the idea of the ordinary person having the option of adding information, not just the experts.
