Completely agree. Well, tf.contrib I am usually happy with the docs and a glance through GitHub issues, but, yes, code found elsewhere for very new, or even just recent papers can be really hit or miss, and not always obviously so. There is a lot of great stuff out there, but sometimes even popular papers over a year old can still be a challenge to find good code for. finding 3 separate implementations, all stlighty wrong or unusable is not uncommon.
