Google is offering a live feed of the conference via (what else?) YouTube. Meanwhile, The Post’s Hayley Tsukayama has a look at what to expect from the show this year the rumor that Google is expected to launch a streaming music service to compete with Spotify.  If you’re wondering what the I/O stands for — it’s input/output — and if you’re wondering why the conference matters, Tsukayama sums it up:

“In the past, I/O has served as the launch pad for Google’s Nexus 7 tablet, the stage for Google’s skydiving demonstration of Google Glass, and has also traditionally been the place where Google unveils its new versions of Android.”
