[Rails] ROR Recipes Beta: Why use taggings instead of tags_contacts? NoMethodError tag_with?

Wow, it feels great to receive a reply from David himself.
  
  Thanks a lot man for the clarification.
  
  You are doing a great job and like other ROR developers, I greatly appreciate your efforts.

Namespace clashes are problematic for packages that wants to be used
concurrently, not for alternatives. How would the situation have
improved if I had called it acts_as_polymorphically_taggable (except
for making jokes about such a terrible, terrible name)? Would we not
have had the same questions as to what does what and why? Of course we
would.

In any case, let me summarize the difference quickly. The main
difference is not plugin vs gem, but rather that my version of
acts_as_taggable is designed to work with multiple classes. So a
single tag can be used in the tagging of multiple classes. This
requires polymorphic associations and join models, which is why it
only works Edge Rails (and will work in the forthcoming 1.1).

So if you need that feature, tagging of multiple classes with the same
tags, then use my version. Otherwise, the old version is probably
better. It's certainly more feature-rich and better documented.
