Saw lots of this in the access logs:
184.108.40.206 - - [08/May/2015:10:37:27 -0700] "GET /blog/archives/2015/02/03/here-and-defending-your-trademarks HTTP/1.1" 200 12324 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/600.2.5 (KHTML, like Gecko) Version/8.0.2 Safari/600.2.5 (Applebot/0.1; +http://www.apple.com/go/applebot)"
So its real — there is an Applebot, and it’s written in Go. Apple also has documentation about it now. And of course, you can read Gruber’s piece. Would be nice to find out ways to feed more info to Siri (I mean, it doesn’t work as well as when its in the USA…).
