It's a great initiative, but I'm pessimist about this. I tried to introduce colleagues to RSS and the reaction I got was "why would I want this, it's inferior to twitter, non interactive etc etc". So it went over the head of those whimsical people, it's possible that I could have explained it better although at that point when they accused me of pushing "obsolete technology" I did not bother anymore. Even to the point where I said that RSS feed on the marketing website needs some improvements the reaction was that it would harm the "social media presence".
My reaction was: "So we are cutting the branch we're sitting on, keep calm and carry on".
Try pushing the non-intermediation angle, perhaps? Tell your colleagues that with RSS you don't have to fight Twitter/FB's algorithms to surface your latest content to users.
Plus, having a proper web feed actually helps with your Google rank as it convinces googlebot that your site is alive.
I usually explain that the people that share stuff on Twitter (or Facebook, or Reddit, or HN) often get their news through RSS. It might not be used by everyone, but it’s used by the users at the centre of the networks you’re trying to reach.
