I would like to have the tags Zemanta is using for a reference able to be manually removed or add to. Sometimes Zemanta is not "getting what I am playing down" so I usually add keywords to my blog that I remove after it finds stuff for me.
Also - the same it true for extra words. I use a friends name "nick" all the time and it tends to give me nickelodeon stuff. Same with Google - if you add that...you get all google stuff. If I could remove tags Zemanta is indexing - that would be very cool.
