This is the introduction-post of my series on using taxonomyfields in SharePoint 2010 development. The series will, besides this introduction, consist of the following parts:

Part I: Declaration and initialization

Part II: Using taxonomy fields programmatically

Part III: Searching taxonomy fields

Read this post from Wictor Wilen to learn (almost) all about it:
