New features, project stale?

[adamico]

Hi,
I've been using the gem for a couple of months and it's perfect for apps needing a simple tags implementation.

I was wondering if users are interested in new features addition or code optimization. I say this since there are a couple of interesting pending pull request or issues.

Since maintainers of mbleigh/acts-as-taggable-on don't seem interested in having Mongoid support (I know the question has been asked before mbleigh/acts-as-taggable-on#228, even it's quite old now) I was wondering whether a "selective fork" of some features of that gem:

1. tags context (skills, languages, hobbies, etc.)
2. tagger model
3. anything else?

I can start working on tags context, even it would require massive refactoring.

The second more obvious question is... is the project stale? I know @calebclark answered to #33, so I think he at least is still interested in maintaining this gem.
What about the other maintainers?
