There are always people that you meet in the startup ecosystem that you discover are PORCUPINES.

The thing about PORCUPINES is that they have their defenses up and are really fine not to have anyone get too close to them.

This may be because of previous bad experiences, fear or personality.

There is nothing wrong with participating in a startup ecosystem if you are a porcupine. Just realize that you have to be willing to share with others to get the most out of the networking and help that others can provide.
