Pinterest is one of the most successful social networks,
that's no doubt, however, has a thorn that could not be removed: their
structure does not allow you to share content with ease, and the 'pins' had to
be sent to family and friends using the (ahem) old e-mail. However, never too
late to catch up and social network allows from now send 'pins' directly to
your friends using mobile applications or web. The email option is still
available for those accustomed to the old school and You can send to your
Facebook friends. Users of the social network also receive notifications of the
reactions of their environment either through phone or by email. Source: Pinterest
