Content Type Hub in SharePoint 2010--(Very Important)

Introduction

1. SharePoint 2010 introduces a new concept called Content Type Hub.
2. This is the way of making centralized content types and re-usable in the SharePoint farm. 
3. With SharePoint 2010, this limitation is resolved and with content type hub feature, content types    can be created and published and can be re-used/shared across the web applications.
4. Content type created in one site collection cannot be shared to other site collections of same web application or another web application in MOSS 2007. 
5.  Finally the site collections present in the web application which subscribes the metadata service will get this content type.
