If you'd like to share a moment with friends then you could take a video, upload it to Facebook or YouTube, wait for friends to find it, then wait a little longer to see what they think.
Or you could just use Twitter's free iOS app Periscope to broadcast it live to your Twitter followers, optionally with location information so viewers get to see exactly where you are.
Your followers get a notification just as soon as you're online. They can add text comments in real time, or send you hearts (the rough equivalent of Facebook Likes) to show their appreciation.
If some people aren't around, that's not a problem - clips can optionally be kept as recorded videos for viewing later.
Or if this is all sounding a little too public, don't worry, you can choose exactly who you'd like to view a particular broadcast, or delete others entirely whenever you like.
