First of all thank you for a wonderful plugin.
It works beautifully for me. I am relatively new to WP and would like to know is it absolutely necessary to make archives and categories "no follow".
I am asking this for two reasons:
1. I now that duplicate content is bad, but I see that "no follow" is not set as default in your plugin.
2. That makes me think that maybe WP is somehow recognized by Google as a blog that by nature has "duplicate" content in for of archives and categories, so it does not get penalized.
In any case, should I check "no follow" or leave it as is?
I would like to hear different experiences from people that are using WP for a longer time than I.
