Love the Edge template, but there are a few very important things missing.
1) GIF uploads are not animated, this is a basic feature of any social site. GIFs should playable.
2) Wall previews - When a user inputs a website address to embed a video from there, it should display a preview, description, etc. as per the current social networks.
3) Being able to create a gallery either public or private for users to upload particular content in each folder.
4) being able to reply to comments on the wall with images.
This is just a few things I have noticed but it's early days, hopefully these won't be far behind.
