Having skipped Instagram, Snapchat and such, I'm surprised to find myself incredibly enthusiastic about Periscope and Meerkat. I really think they're onto something here.

I've watched a number of streams of people showing things they're working on, streams of events people are at, etc. It's incredible - you feel like you're there, participating even. Live streaming has existed for years, but it has never been this easy to create streams and view streams. Just hit a button and you're showing what you're seeing to your Twitter followers. Or, if you're browsing Twitter, tap a link and you're seeing what they're seeing.

I'm especially looking forward to events such as WWDC, Google I/O, CES, etc: will be fascinating to get realtime access.
