At first I thought the KDE apps all playing on the K was kinda weird and awkward, but as time went on I really appreciated how easy it was to search for them due to this. So I really think it's a benefit to play on traditional words rather than use them as-is.
jjplace/jjhub/codetown, whatever. Doesn't matter.
Names don't matter that much for brands. Names just have to be simple enough to remember (ideally two syllables or less). What the heck does Nike mean, for example? Boeing is just someone's name. Microsoft is just two words smashed together. A brand's name literally doesn't matter.
I would guess under 10%, and only that high because Nike sells shoes in Greece and Italy.
