Feedient is a website that aggregates all of your social streams into one place. It makes it easy for you to keep up to date, even allowing interactions on each unique channel. The channels so far include Facebook, Twitter, Instagram and YouTube.
Ok, so NO ONE checks Instagram on desktop, but still, having Facebook and Twitter rolled into one can save some browser tab real estate. It might even save you from having your boss see your Twitter and Facebook tabs open...it's ok, you can thank us later.
