Besides obviously agreeing with this, I thought I’d give a recent real-world example and kudos to RIMarkable for switching to full-content feeds.

I’d actually unsubscribed from the RIMarkable feed because it was excerpt only (and e-mailed them to tell them why), because other BlackBerry blog sites did offer full content feeds. When RIMarkable switched to full content, Robb took the time to reply to my mail and let me know they had done so – I promptly re-subscribed.
