I like that it's simple for my customers, since they don't have any technical knowledge or skills required! Also i love how easy this software makes our lives as marketers easier by capturing all kinds of information from social networks (Facebook) we can use them later with other tools such us Mailchimp etc..
My only dislike about opt intelligence would be its price because you need some budget before using but after testing several times -it was worth every penny spent- there are no disadvantages at least so far!! It helps me easily connect more people around specific topics which results into sales opportunities thanks again :).
