I thought (hoped!) this would be a full text database of Oleg's papers (http://okmij.org/ftp/), though of course the irony of constructing such a beast in Go would be overwhelming. As it was I found the website only a marginally less enjoyable read than "Finally Tagless".
I assume this is getting up-votes by appealing to HN's current infatuation with Go, but would be genuinely be interested to know other salient points of the project beyond its laugh value.
