Lifehacker is a great site. The bulk of its content can directly improve your daily productivity. A lot of it is quite technical, in terms of how to use technology to be productive, but there’s plenty of “general interest” discussions as well.

For those keeping score that’s 73 total submissions.

And although the flow of submissions has slowed somewhat, I’m still seeing a handful or more per day. Hopefully more people pick up on the group writing project meme, write their best productivity tips, and tag others. Once we hit 100 or so I plan on getting the e-book going…
