I use; Workflowy, Product hunt, basecamp, linkedin and skitch extensively.
And also been using my own platform Cobeats.com for quite a while now. People who are found of using Evernote, I would highly recommend a better evernote in making Cobeats.com (http://www.cobeats.com/). Better could be less in feature sometimes, play around guys!
We are in our closed beta ATM and published our android app recently
