Do you think more delegation is a good solution to the problem? Giving the creators the same powers as the investors so that they can shape the community to their benefit, thus attracting more users and creating more value based on output rather than speculation. At least this provides mutual benefit to the delegator and the delegatee. 

There will always be a mix of short term traders and long term investors,  I am just not sure in what proportions though... so it will be interesting to revisit this post in another 6-12 months time.
