My favourite search engine is 
Google. My favourite stop-off for quick information is 
Wikipedia, the free encyclopedia If I see an actor in something and it's annoying me that I can't remember where he's from then I use 
The Internet Movie Database (IMDb). If I want to catch up on an episode of a TV show I missed, or just feel like some dubbed Japanese anime, then it's 
alloftv.net But the site I use most is 
LCNA ~ Extreme Mafia Roleplaying!. It's the least mainstream of the sites I've listed, but for that reason, it's one of my favourite finds. It's a mafia-themed roleplaying site. Quite a lot of fun if you're into that kind of thing. Though I should warn you, don't get into it unless you have plenty of free time, because it is very addictive!
