Should I index tag pages?

Should I exclude the tag pages? Or should I go ahead and keep them indexed? Is there a general opinion on this topic?

Recently had the same issue and we went with not indexing them. Two issues mainly - the duplicate content issue (same results being attributed to author, posts, categories etc - which i don't believe is too much of a problem. The other one though was the general titles being attribute to the results were pretty average.

We tested both indexing of and excluding and didnt see any increase in traffic with them, so went with the exclude option.

Hope it helps. Good luck.
