a Facebook "like" or Twitter "follow" system - in Rails 3
===

Can anyone point me in the right direction to learn about how I could implement a system similar to facebook's "like" or Twitter's "Follow/Unfollow" system that i could create in Rails?

From what i understand i would need to use Unobtrusive Javascript.

I have a Thing model(has_many :likes) and a Like model (belongs_to :thing)

Any pointers?

Cheers,

Adam
