Has nothing new to say, yes GO's GC fragments heap, is slower at 
allocation and adds "read/write barriers from hell". But it does 
optimize for short pauses, which in turn avoids ugly spikes in server 
workloads and that is priceless. I have had the pleasure of trying to 
"tune away" the GC spikes of Java cluster software - it's not pleasant.

I agree with your view on this one. Go puts both advanced and novice 
programmers on the same ground - both have to write dumb code with 
little to no abstraction. In my limited time with Go I found it futile 
to abstract away even the most trivial patterns such as map-reduce with 
concurrency.
