I love that you can create your own social media channels, but also use all of their existing tools to promote them! You're not limited in what type of content or style/looks for each channel - it's completely up to YOU!! The ability is there if one day they decide to limit access without telling anyone about this change (which has happened before).
That would be my only dislike so far; however, nothing too terrible at least yet. It takes some time getting used to how everything works since we are just starting out with creating our marketing plan. However once learned its great fun using these platforms especially when promoting new products like ours :).
