I guess "just Google for Mu" won't work any more. Beginner coders are just gonna love "Firmware as a service". ;-)
And it never did work for such an ambiguous term (greek letter? Micron Technology stocks? Manchester United?), unless you googled "mu editor" in which case you're still fine.
Has it so far? Did you say "Mu"? In that case people could have googled for all kinds of things: Mew or moo or me or something else. And even if they knew how it is spelled the first results would have been the greek letter mu, the zen mu, or the football team Manchester United. In Sweden a lot of the results were about a children's tv-programme, Mamma Mu.
Your editor is not on the first, second or third page of Google, I didn't look any further, because who does?
It's probably good for you that you realised saying "just Google for Mu" won't work "anymore".
Sidenote: If you want a unique name don't pick one that is 2 letters (or 1 technically).
Reminds all over the GVFS story again:
1. GVFS name is trivial, but less trivial than just "Mu"
2. Mu Project vs. Mu Editor makes it still distinguishable
3. GVFS (now gio?) exists for ages, Mu Editor and Project Mu are two fairly new projects.
I guess I'm just still upset about how people at Microsoft picked the name back then and how little they initially considered changing their name.
You can see what folks have been doing with Mu (the editor) here: https://madewith.mu/ :-)
