I haven’t seen anything about “mobile being dead” as most are still saying it’s the next big thing (see Mary Meeker’s annual ‘deck’ for the past 8 years.) On the other hand, many are still shouting that RSS is dead… meanwhile, I thought your solution for a shared feedly collection for following a whole classes’ worth of blogs was fantastic, and that was only available courtesy of RSS!
On the topic of your annotated bibliography, you might consider looking at the http://www.genius.com platform. Formerly more music focused and named RapGenius, A while back I wrote about some of their functionality here http://boffosocko.com/2014/04/08/rap-genius/
As an aside, on general technology related issues, if you’re not already following them, some of my favorite sources for ed tech include:
