Possibly following something twitter does or doing it another way;
Opening up every single profile you want to follow to do so can be annoying, especially with this site just beginning and most of the people you're following being people you already know and happen to see your friends following.
This is why I purpose in some way, the ability to Follow someone and possibly complete other actions, via their icon.
One way is twitter's mini profile thing that appears on Icon hover which works very well. Also possibly just having the buttons just bellow the names or in one of the bottom corners embedded into the Icon.
The same with submissions as well. In fact it would be easy to implement with submissions, as submissions already have the icons for their actions overlayed (fave comment etc), however right now clicking them just clicks on the image behind. Hovering over them shows the quantity of each thing however, and that means it most likely would be easy to give them a clickable function as well.
Many people use favorites as a way of coming back to submissions or posts to look at them later and may even gloss over a post because they don't want to wait for it to open to do so.
