Buffer bills itself as a smarter way to share links to Facebook, Twitter and LinkedIn.
It schedules posts over a day or week and sends them at a time to suit you.
This means you send links over a few hours rather than all at once. You can then concentrate on engaging with people rather than composing links.
It also give you lots of analytics and intergration (you can post direct from Google and Safari)
