This sounds about right, if not a little earlier. Experimental work for this was done by me here: https://github.com/ianvanness/html5history

I believe there were further tweaks for additional pages that needed to be supported (whereas I had only solved, and most likely not very elegantly, the rudimentary issue) that took additional time before the hash bang removal was actually launched.

Thanks - I was estimating off the top of my head - the site was in flux for a while at the time. They also went back and forward with keeping the story sidebar at fixed positioning and it seems they settled on it not floating.

I check the site every couple of weeks because I was interested in how the redesign would work out. It seems they eventually got it right, I like it. A lot of the other blogs have home and article pages that are just too heavy and slow.
