In the browser and on my phone I use: Google Reader, Twitter, and a little bit of Facebook. My Google Reader has something like 150 sources and I generally skim the headlines of all them together. If I've tapped that source I'll head to Techmeme and HN directly.

On my iPad I subscribe to The Economist and I also use Flipboard (again, with Google Reader).

Via shared links on Twitter and Facebook I generally end up on the NY Times a few times a week, as well as the WSJ and Wired.
