Normally, I am not a fan of replacing words in the search engine with computer science stuff (think AJAX), but I can accept computer words replacing words that symbolize violence.
Your results, even when logged out, are heavily biased towards your previous query genres. For instance, I'm not logged in, but am at home with an IP address that hasn't changed in over a year despite being leased. When I search Google for the term "Ruby", the entire first page is for the Ruby programing language.
My father works with jewelry. Last week while visiting him, I did in fact search for the term "Ruby" on his computer in his normal browser, and even though he was also logged out, I wasn't able to find one result dealing with the programming language on the first two pages.
Google understands that Ruby can mean different things to different people, although I don't think it's gotten there with "ied" yet (and rightfully so, it's probably not searched for very often, except in the violent sense)
Yeah this was just a soft-launch for MWC. We're planning a proper launch soon with more context for the user, proper feature detection, categories, etc.
The goal is to get something decent on all browsers--and we'll open the repo on github for those who want to help us get there.
I don't think you understand how prefixes are used in the wild. Vendor prefixes re-inforce monoculture, they don't prevent it.
