This overview gives you an idea why people use Channel.
I use channel with my students; we make comments on news and read texts together. And we combine it with Skype.
I've created a channel with my friends, they join every night and we discuss and share music we found on YouTube.
There are other tools available but with Channel you can actually surf on the YouTube website together.
In a physical world shopping is a social experience. Channel makes it easy to shop with your friends online. Ask a friend for an opinion and get direct feedback on what to buy or not.
