I used Hueman Pro for the year I had my own blogging website. It was easy to use and navigate, looked very sneaking to myself and to visiters. Review collected by and hosted on G2.com.

The cost. Obviously it will likely work better for more business oriented websites and therefore the cost wouldn't be something to gawk at, however, it wasn't overly beneficial to me as a blog. Review collected by and hosted on G2.com.
