@hamatti For sure, if you have such a great luck to have such a team. But when people change projects and teams, how often all of the team members have so much extra time to keep up with the scene, if work schedules don't have enough flexibility for the learning? Not everything can be outsourced to personal learning time outside of the work, if it is directly related to the work.
My main worry is that while this kind of shared RSS feeds could be useful for improving learning in a longer term (product/service focused) teams, it likely wouldn't work that well in a consultancy environment where people come and go constantly from one project to another (with completely different technology requirements).
