You forgot to mention inbox tools that make the email environment pleasant, enjoyable, and efficient! I learned about an amazing browser extension called PowerInbox ( – it lets me interact with the content of my emails right inside the emails themselves. When i get an Instagram email, I can now view, comment, and like the photos via Instagram inside that email itself! It’s amazing and not even limited to Instagram emails – they support LinkedIn, Facebook, Twitter, Groupon, FollowUp, and many more! Using their email apps is just like using apps on my iphone! Their blog can be found at – I’d recommend it!! But interestingly enough, Instagram photo-engagement didn’t end there. With their introduction of Sidebar, I can log into my Instagram account and see my entire feed of photos, view all likes and comments by other Instagram users, and comment back and like the photos right there, immediately.
