Without doing any cost-benefit analysis, I can tell you that, of the three so far, this one gives me by far the most fuzzies, just thinking about it. A scholarly wiki? Boring. Research? Boring. Short primers on crucial topics??? That sounded less boring in my head.

I couldn't tell you why this happened. Maybe I just really liked Facing the Singularity more than I realized. Does anyone else have a similar reaction?
