As a pro, the Grammy's would not have been the same without being on Twitter while watching it. Being on Twitter while watching an awards show is like one giant viewing party. I love feeling a community vibe and seeing what other people are thinking about what I'm watching while I'm watching it. And in this case, Twitter made the Grammy's much more entertaining for me. Did anyone else feel like they were lacking this year?
On the other hand, if I'm tweeting while I'm watching, then I'm guaranteed to be missing something. I don't catch all the same nuances in a show as I would if my full attention was on it, and it's easy to miss plot points.
I'm going to try to make a habit of putting more focus into the TV show I'm watching, and save the tweeting for commercials more often, especially with shows that I feel like offer a lot in the way of nuances and imagery: Alcatraz, Mad Men, Shameless. There are other shows however, that just feel better to watch in a "group," award shows and Glee in particular.
