Since Google Reader was killed, RSS has seen quite a boost, with a ton of new platforms jumping in or existing ones adding support. If this is not a sign that RSS functionality is truly important and very relevant, I don't know what is. I for my part was planning to turn one of my notebooks into an RSS feed for months. Last time I checked, the feature was still alive and kicking. Based on this knowledge, I started to integrate Evernote more into my workflows, assuming that when the time was right, I could enable RSS sharing. Now that I'm actually there, the feature is gone. Apparently without any prior notice. For free customers, this must be annoying. For me (I'm a paying customer), this is beyond frustrating. I feel betrayed.
