Well, since i didn't want to step on the toes of boorkmarks because many people consider their bookmarks as more of private note taking of stuff they wanna go back to, and I wanted to invite people to not worry about crosspollination, I had to go with application specific Kinds 30077-30079 for wall indexing and configurations and 30081 for Pin sets. Other than that reutilized others like 39089 Follow packs Kind when you want to create a follow pack of all the users pinned in a specific wall, and other general NIPS and kinds that are the standard.

The hardest choice was opting out of using bookmarks Kind for pins, but when i started testing it became obvious for me that it felt a better option to go with an application specifid kind . And only use Bookmarks so that users can see their own bookmarks in the landing page and choose if they want to pin any to specific walls.

In any case, I shall learn wether it was better soon enough. :S
