I don't really use apps on my chromebook so all of my everyday computing is via browser and here are the tabs I have/keep open all day every day:
- newsblur.com (my rss/reddit reader)
I actually divide my screen into two 'windows'. One is a column of nothing but Tweetdeck. Twitter scrolls through there all day long. The rest is one window browser of the other tabs. Plus, tabs of whatever catches my fancy that day.
