I think the small daily reward dopamine rush is needed for people who aren't emotionally committed to the site.

As I understand it, the rules are basically the same, except that the scores are applied over a month instead of a day.

On average, people should be getting a similar amount to what they would have gotten with daily rewards. However, I think it's going to skew towards established stackers and work against newbies.

I don't really understand the rules of MSM and I suspect it's too complicated for newbies.  I preferred the daily rewards which I also think would help retain new users.
