If you have ever decided to make a blank site just because you know your going to start from scratch then find out that alot of the features your used to in a team site simply arn’t available or don’t work as they do in the team site? SharePoint has a number of hidden features which you can’t activate via the interface. If you have decided to use managed meta data and run into issues then its probably because the hidden “TaxonomyFieldAdded” feature isn’t available.
