According to Google Trends, during the past few years, there has been nothing but a few minor bumps that faded away as quickly as they came. I love RSS because i do not have to scroll through dozens of different news sites all day and i would love it to return.
EDIT: Typical case of people only reading the headline. I was asking why people are hyped over something that did NOT happen.
Sounds interesting, especially with the fact you can comment on it. Only issue is getting sites to adopt it, and currently RSS is just dead simple to implement.
