I like that they are very user friendly which makes it easy to upload images from both my computer as well as other online sources such as Flickr or Facebook. They also provide many templates depending in what type of photography you do so this helps make things easier when uploading your work with them! Nothing really at all but maybe just try out their site before signing up if possible? Do some research first because there isn't much customer service (as helpful) available once signed into the system. It would be nice if we could have help via email sometimes too instead of relying mainly only through social media. There's no way around having multiple accounts though; however since everything goes straight onto one account it can get overwhelming trying to manage all your clients' sites. The benefits include being able to see each client individually without needing another person managing separate websites.
