Internet time-sucks

A selection of various websites for you to get lost in for several hours:

Sweet Tooth. This has been sitting open in my browser for three days so I can drool at it whenever I want.

Reasoning With Vampires. Dissecting passages from the Twilight series and explaining what makes them such poor writing. Intelligently.

Zenni Optical. Their virtual try-on feature is really easy to use, and you were feeling narcissistic anyway. The most expensive pair of glasses they sell is $46. What?!

Pinterest. Have you joined yet? If not, maybe wait until you have several hours to sit and stare at lovely images in a gloriously mindless state. (I'm a member but am not sharing my id because it's linked to other shit in my real life and I'm a paranoid weirdo, but it's mostly pictures of knitted housewares, fancy-pants recipes photographed well, and home-type shit I can't afford.)

Books to challenge preconceived notions, via Metafilter. I'm pretty sure I haven't shared this yet (and am too lazy to check, sorry). So many good books to add to my list!

Now you share yours!
