Up or down Periscope?

<p>The phrase in many a heroic maritime movie was ‘up periscope’. A more contemporary version is the Periscope app.</p> <p>It marks the introduction of Twitter’s livestream broadcast app, Periscope.</p> <p>In simple terms it permits Twitter users to initiate a live broadcast of whatever they desire, from a live feed of live animals feeding to an earthquake from anywhere in the world.</p> <p>Twitter users will be able to switch from one stream to another, at will.</p> <p>Periscope’s live data can be shot using iPhone or iPads and viewed via smartphones or laptops. </p> <p>To use the app you need a Twitter account and once you have Periscope downloaded you will be asked if you want to subscribe to the broadcasts of those individuals you follow on Twitter.</p> <p>Then you are ready to stream and receive.</p> <p><blockquote class="twitter-tweet" lang="es"><p>Introducing <a href="https://twitter.com/periscopeco">@periscopeco</a>, a new app to share & experience live video from your mobile phone: <a href="https://t.co/Vl3S6SWsIC">https://t.co/Vl3S6SWsIC</a> <a href="http://t.co/suYRezE5pb">pic.twitter.com/suYRezE5pb</a></p>— Twitter (@twitter) <a href="https://twitter.com/twitter/status/581094219575627776">marzo 26, 2015</a></blockquote> <script async src="//platform.twitter.com/widgets.js" charset="utf-8"></script></p> <p>Now in this brave new social media world, danger lurks. </p> <p>Sex predators, paedophiles, stalkers, snoops, cops, psychos and bailiffs are watching through a window directly into your world.</p> <p>For a father unable to attend his child’s fifth birthday party it provides a moment of warmth to treasure, but to a paedophile….</p> <p>Periscope has an additional feature: while watching a stream you can type a message to the streamer and fellow watchers, both complimentary or abusive.</p> <p>In an attempt to counter problems, location tagging can be disabled, but if not the app will provide any undesirable with precise directions to where you live, work or play. </p> <p>On the plus side Periscope can provide invaluable footage of wars, crimes, natural disasters and exploitation.</p> <p>There are other apps that perform similar functions, but this is Twitter and when Twitter talks people listen then tweet.</p> <p>So like in all things caution is advised.</p> <p>So you chose: up Periscope or down Periscope?</p>
