Today, I've just finished my first Alexa app, to stream the station, and submitted it for certification and approval to Amazon. It was a fairly painless process, using a template by the good folks at Dabble Labs, and their "Audio Streaming Example".
It is another way to expand the footprint and listenership of the station, when over-air might not fit the bill.
I'm glad that I've gotten you thinking. If I had known creating the skill was going to be as easy as it was, I would have done it sooner.
The only thing I wish that I could, easily, include is NowPlaying information. I guess that is something that I'll have to look into.
BTW, if there is anyone who would like to include Nowplaying information, from their streaming station, or combination streaming/on-air station, like mine, on Twitter, I would recommend and easy free way of doing so, if you have the bandwidth. It does require a third party app, but it is free, called WACUP, which is much like WinAmp (but recently updated).
