Yes, I'm hoping to get started on a completely new type of  reputation system later this year.

This time, I am thinking about doing a relatively small hardfork, feature-wise, in order to reduce the time to test and deploy it a bit, but not at all sure yet. Hopefully, I'll be able to include some of my ideas for the hardfork in our next update post. Two I can think of right off hand are option for accelerated power down for a fee and a change to speedup transaction finality.

But you can post about ideas for new changes anytime you like. While I don't always comment, I always look over the ideas posted in the "Hive Improvements" community.
