The Thinking Sideways Podcast - Three people attempt to solve mysteries. Some are serious. Some are weird. It's always interesting.

We Hate Movies Podcast - Three New York guys talk about bad movies. Totally different than the one below this.

The Flophouse Podcast - Three New York guys talk about bad movies. Totally different than the one above this.

No Such Thing as a Fish - The Q.I. Podcast - four Q.I. researchers discuss interesting facts and get very silly.

We Have Concerns - We Have Concerns is a short, improvised podcast about the wonder and dread hidden in everyday things (their description). One of the best things about this podcasts are the improvised scenes. The one that really sold me was the Space Ref episode. Seriously go listen to it. Another great thing about it is it's new ALL THE TIME. Three a week!

The No Sleep Podcast - Horror fiction. Short stories, mostly (entirely?) from /r/NoSleep (Reddit). Some stories are excellent. Some are so-so. All of the narrators are great.

Pajiba - A Pop Culture Website. This is one place where it's absolutely safe to read the comments. Some of the best people I've ever seen online are regulars here. Lots of smart, funny, snarky people. Oh, the articles are good too. 

TVTropes - The official timesink of the Internet. Go on. Click the Random button. But tell your loved ones goodbye first, because they won't see you for a while.
