Pinterest ends invite-only policy

  • Image-based social network site Pinterest has stopped its sign-up policy and opened the service to all.

    Previously, people needed invites to become members and "pin" online images onto its virtual "boards".

    Pinterest was launched in 2010 and became the fastest-growing site ever with 10 million users in nine months.

    The company has tried different money-raising techniques but is yet to disclose a commercial plan.
