<i>There weren&#x27;t many when it began, but today we have Google-plus, twitter, Reddit, Hacker-news and lots of others</i><p>That&#x27;s not the real threat to Facebook&#x27;s empire. Those are all tools used by people in their late 20s and 30s who came of age in a desktop-first world and Facebook is comfortable coexisting with them.<p>The thing that is a threat to Facebook long term is mobie apps like Snapchat, YikYak and other things we old farts haven&#x27;t even heard of. They are used by (and represent) a new generation of truly mobile-first users for whom Facebook is something their parents (&quot;old people&quot;) use. The biggest risk Facebook has with these users is not that it just unused, but uncool.
