Sharing on social media is functionality that should be built into browsers or implemented with browser plugins (it should be a single click on some browser toolbar). There's no point in replicating it on every web site in a performance-hampering and intrusive way.
Interesting point. The default Android browser (at least the one on my increasingly dated Droid device) has a "share" menu item. The only things I use it for are to email myself articles or to post links to Readability.
The whole "Social" thing is .... largely annoying.
Yup, Chrome on my Nexus 5 also has the Share menu, and with the Facebook & Twitter apps installed (and also some App.Net clients), they all appear in the Share menu. It works well. On the desktop I use the Pocket & Buffer extensions instead.
Of course, out of sight, out of mind - if your audience isn't tech savvy, perhaps they need that visible reminder to share something.
