I feel like everyone thinks 'man you need an advisory board to be considered real.' Most meetings with anyone investing in you they ask 'who is on your board.' Even with all that being said, I just don't see the value. Most people will help you along your way because they care about what you are doing. The ones that want something from you in return, I would stay away from anyway. Either way, like hwijaya said, its all up to you.
