"Top" is the pronunciation of the Chinese word for "breakthrough," but of course it's also the English word for the highest point, the apex, the pinnacle of something. Like being at the top of one's game, the top of the market, you know, the kind of position you'll be in after you break through.
Good news for breakthroughs and those already on top, then, because .top domains are on sale until the end of this year for creations and renewals. Though they normally cost $27.37 for one year at A rates, you can register one for just $1.99 (also at A rates). Renewals, normally $27.37 will be available for $9.00 per year.
