Tagging suggestions?

[Mike Doel]

So, I'm still fairly new to Rais as a framework.  And I'm trying to build a fairly simple app that's not unlike a blog with posts and tags.

Has someone done tagging in their Rails app and do you have thoughts on the best practice for adding this?  I see that there's an acts_as_taggable and acts_as_taggable_on_steroids plugins available.  Alternatively, I could try to create a separate Tag model and setup a HABTM type relationship between the posts and tags.

Any experience which suggests the pro's and con's with either approach?

Thanks in advance.

Mike
