Twitter

I can certainly see how people can benefit from Twitter; but I can also see the danger of getting caught up in the Twitter culture. I personally have no interest in pursuing the use of this source.

Do you find "Library Thing" user-friendly?

I enjoyed exploring this site and found it to be quite user-friendly. There is a great deal of information about all of the authors I chose. I do prefer to find books through person to person suggestions however. Since I spend none of my spare time on the computer I would use more traditional methods of finding reading material.

Would I use Scrybe, Google calender etc.

I certainly would not find any of these sites useful ; I would prefer to use more traditional methods of time-keeping and date keeping. I certainly can see the benefit of the Google Docs if I were a student, however. It is certainly worth knowing about such a service.

Did I find Youtube and Flickr user-friendly?

I would have to say I have found Youtube to be particularly useful A case in point was when a customer needed the exact musical version of the "Friendly Giant" theme song,. We could not find it on a recording and a collegue of mine suggested Google which then led us to Youtube. The customer was over the moon at being able to hear the exact version, so that she could reproduce that version at a wedding on her harp.
I can certainly understand why people use Flickr and I found it easy to navigate, even though I cannot see it as something I would spend much time using.
