Commitments and Contingencies [Abstract]
Commitments and Contingencies	9. Commitments and Contingencies After the completion of the Company’s acquisition of PowerReviews, the Department of Justice, Antitrust Division, notified the Company that it has opened an investigation to determine whether the acquisition violated Section 7 of the Clayton Act, 15 U.S.C. Section 18. Because the investigation is in an early stage, it is not possible to reliably predict the outcome of the investigation. Therefore, the Company cannot currently estimate the loss, if any, associated with the investigation.

The entire disclosure for commitments and contingencies.
