The trouble with this kind of pages is that there is no real content, only external content. I'm aware of SL's free policy, but this feels odd - similar to go servers that don't care to setup their own wikis even if they most probably have the means, but use SL - also to better promote their presence.
With all respect for Robert Jasiek, and understanding that it is not easy to condense the matters (and much easier to do the work once, at "home") (and this avoids any form of "mutilation"), yet it feels like there is no "meat" here, only a few bones.
If all pages would be like this one, there would be no wiki concept anymore.

Looking better, but still depending on important external content ...
Acceptable
But then... there's lot's of interesting Go content that's not on SL. E.g. http://www.gobase.org/studying/articles/matthews/ko/ etc...
