Here are a couple of things that I think will improve the social sharing integration:
1) Allow for individual image uploading per social platform - currently, the one image fits all doesn't work on all the social platforms because they display images differently. If not individual images per platform, then allow us to edit the single image for the different platforms.
2) Have a date stamp on the social post automatically, so we can see when the review was made, how are customers supposed to trust reviews if they could have been from 5 years ago.
3) Have a name on the review automatically when sharing on social - Currently, if looks like I'm recommending myself in the review, rather then being recommended by an individual customer.
4) Integrate with more social networks.
5) Allow additional text to be added or for the review to be more like a quote - so we can respond positively to the social post.
