Way back in 2006 Typepad added Technorati tagging to blog posts.
I used this as a way to add tags that I didn't want to make full categories, most recently a lot of Twitter hashtags.
However, Technorati was acquired by Synacor this year (2016) so it seems that the tag functionality is going by the wayside.
I have therefore removed display of Technorati tagging. You can find this in Typepad controls under Design->Content - Post Footer - Technorati Tags.
