Now we have ♫.ws, also known as The Unmentionable Musical Symbol.
According to this story in Wired online—where the musical symbol got scrambled into a question mark, and the link goes nowhere—♫.ws is a music search engine for Twitter users. It was developed by Sawhorse Media, which also created Musebin, "a site for Twitter-style music reviews," according to Wired.
Sawhorse Media has a nice handmade ring to it. Musebin isn't bad. But two eighth notes? At least tell us which key they're in.
It's hard to build word of mouth when you don't have a word.
Hat tip: Anthony Shore.
And .ws? It's the country domain of Samoa, formerly known as Western Samoa.
