a bit of all that:

  * Chronicling the products that were created.

  * Having a forum where there is discussion on the MVPs created, to validate it against real market and see if it can be developed into a product.

  * A place where the MVP creators can try to find initial customers / beta testers.

Individual networking does not required any post event hand holding, but thats hardly enough to help the MVP to take shape into a full blown product.
