I appreciate your follow up. I couple of things did happen with other projects too:

• one is that one of the better versions of Anki did get created - you can see up in the newer comments somewhere, where it was linked by hacker news.

• Peter is also collaborating with someone working on his version, although I don't know whether or not this post had a impact on their collaboration.

• I worked for awhile with one of the people Eliezer mentioned.

• The backwards kickstarter folks were talking for awhile, and someone ended up working on a similar project with another group - I haven't followed up with them.

I think its likely that other stuff happened - I only found out about the better-Anki program because I ran into the guy who was behind it at a party. Likewise with my post about starting group houses - I know of several group houses that started that used it as part of their process, but I think only one commented. The co-working post has also been very successful, although not in the way I had anticipated - I don't know of much in the way of individual partnerships created, but the study hall that started is still going and populated almost 24/7, several months later.
