Back from Las Vegas

So the blog has been getting around quite a bit lately. I just returned from three days at a journalism convention in Las Vegas. The convention was put on by the Society of Professional Journalists. Yes, I did have some fun, but more importantly I participated in about four workshops every day and almost all of them were about social media (like Facebook and Twitter), blogging and multi-platform journalism (combining writing and video for instance).
So now I'm curious: how do you use the Internet? What are your favorite sites? What's your Internet routine like - are there certain sites you check every day, like news, weather, shopping or hobby related sites?
Do you use Twitter?
Which one is your favorite search engine and why?
