Ask HN: Sites/non-web things you use?

I think this is an insteresting question. I was originally going to post it in reply to a comment to why companies use degrees as filter, but then I decided I'd like to know what the other people on HN use. I might learn something.

1.) List the top 3 sites/things you visit/use daily (don't want to miss these things. like news sites, facebook, youtube, twitter, newspaper, talk show).

2.) The top 3 (non search, ask) resources (books, data collections).

3.) The 3 sites/things you waste time on.

4.) The top 3 places you go when you need help.

I would say:

1.) Linux Today, Slashdot, and Hacker news.

2.) safari.oreilly.com, IBM developerworks, my personal library.

3.) HN, Web Comics, Instant Messaging

4.) Google, Gentoo Forums, IRC (freenode).
