I remember reaching out to them a couple years ago asking about their stack, and I got a really nice/informative response back (actually they linked me to a page on their site that listed all the info). These two deserve it!
A lot Brits say 'naff' when they mean 'unfashionable', it sounds ludicrous to me- as if we were still in the 1980's ( http://en.wikipedia.org/wiki/1980s ). Not fly.
(to be more serious about it: different countries use different phrases. So what?)
They mean different things - reaching out is more specific about who is initiating the conversation, and it also doesn't necessarily imply success. I may have reached out to Bill Gates yesterday to see if he fancies giving me some career advice, but it's unlikely I talked to Bill Gates yesterday.
