The meaning of the word "top" (adjective) is globally recognized a synonym for "best", "high-end", "leading", "highest (rank / quality / position)", "state-of-the-art", "outstanding" etc. in a large number of (western) languages. This plus its easy spelling makes it one of the most used expressions in print / radio / TV / web when it comes to pointing out how something is valued. In opposite to the generic 3 letter TLDs .com / .net & .org which are all abbreviations that stand for "commercial" / "network" & "organization", the generic 3 letter TLD .top is a complete word, "top".
