Personally, I am interested in the Coupon/Check-in convergence. When people are checking in, give them a reason too. I think FourSquare should see huge revenue from this if they play their cards correct... What about a Groupon/FourSquare Merger? Going to be interesting to say the least. 

With larger and more powerful phones and ipads, I also think that the web will continue to go more mobile. Real time satisfaction adn online/offline interaction will start to occur. Location will be everything...

Lastly, the article did not cover this, but mobile payments are here to stay as well. Square just got a huge round of cash nad others are spending tons of times on applications. 

This is the year of walking into the local coffee shop, checking-in, getting a coupon for doing so, and then paying via a quick wave of the iphone...
