Google Calendar

I can see how using Google Calendar would be preferable to paying for Microsoft software, but I still use an agenda made from recycled paper.

YouTube

I love youtube for one reason: I can watch Kids In The Hall sketches while I eat my breakfast. I have only ever used this website for entertainment, and I find it very user-friendly. I also like that people can upload funny home videos, like the 3 year old that summarized Star Wars.

RSS

Personally, I don't spend enough time on the internet to make using the RSS feed worthwhile. If I visited a large number of websites it would obviously help save time - but I don't, so it doesn't.

Google Books

I found this product interesting, but only in a purely theoretical sense. I do not find the prospect of reading a text off a screen appealing, but I suppose I would suggest it as a resource for quick reference work.

Facebook

I think that facebook can be both useful and a time-waster, it completely depends on the user.

Wikipedia

I went to the entry on Virginia Woolf and added a fact, which I was surprised was missing, so I suppose I didn't find it difficult to find an entry that needed editing. I was surprised at how easy it was to edit an article.

Not to my taste

While Delicious seems useful for organizing your own favourite websites and discovering others, I don't find it very user-friendly.
