Twitter

I think twitter is the strangest thing on the internet. I'm sure there are useful aspects to this service, but the majority of the "tweets" I have seen don't interest me enough to subscribe.

LibraryThing

I found this website very user-friendly and easy to navigate.

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.
