Social Networking sites

Digg is amazing! I could sit there all day looking at all the photos and reading all the stories etc...if I didn't have to do other things (like work) of course :-) I signed up to this site and will definitely be a regular visitor in future - it is a great way to find out what's happening in the world and to expand your general knowledge etc. I read the story "What's a hulu? The origins of 8 High-Tech Names" from the "Popular" pages, and learnt the origin of names like TiVo, Bluetooth, Blackberry and Wii etc. I'd heard of the latter three but hadn't heard of TiVo so that is another bit of technology I am now aware of :-) I also read a story from the Science pages "Extremely rare bird photgraphed for the first time - then eaten," about a Worcesters' Buttonquail which was thought to be extinct. Then one was found in the Phillipines and videoed and photgraphed before it was cooked and eaten! Amazing! And such a shame...I couldn't quite believe it! And I can now say I have seen a 100 billion dollar note...under the Lifestyle pages, there is a photo labelled 3 eggs cost...3 eggs are shown above a 100 billion dollar note supposedly from the Reserve Bank of Zimbabwe - I'd really like to know if that banknote was real! I'll have to follow up on that one...I also signed up to Stumble Upon and now have the Stumble toolbar installed on my home computer...and using the toolbar and my selected interests I stumbled upon Scribbler, where you can do scribble drawings, and "Collected quotes from Albert Einstein" - my fav quote was "Imagination is more important than knowledge", and I believe it is 'cos with knowledge but without imagination, I am sure that many of these web 2.0 technologies would not have been invented in the first place. I have set Scribbler and the Einstein quotes to My Favourites, and I am sure I will be stumbling upon many more interesting websites/webpages using Stumble Upon...and saving them to My Favourites...the only problem is that I am likely to end up with hundreds and thousands of websites/webpages listed under My Favourites! ...if my computer will store so many! :-) I also joined up to Reddit and read about an asteroid that recently came very close to Earth. And I joined up to Newsvine and read the story of the attack on the Sri Lankan cricket team. So I now have all the news and articles I could want just sitting their at my fingertips. I really enjoyed all these sites.
