Good work, committment phase for this proposal is growing steadily.
Just wondering, how are people learning about this proposal?
I found it by browsing Area 51 proposals.
I invited one person to commit, and he did. Now it appears that I have three people referred. I don't know personally the other two. I guess they saw this.
I've mentioned this on the Google+ Economics community and the Reddit /r/Economics thread.
I didn't use a referral link, but I'd imagine a good number came from those two sources since I've seen a pretty decent bump after each one.
