From a CNET article on the acquisition:
Kessler noted that eBay has probably made more acquisitions over the past 12 to 18 months than it did in the prior eight or nine years, and that’s often a sign that growth will be slowing. Unlike the PayPal merger, which Kessler supported back in 2002, it is debatable whether eBay will derive the same growth in sales simply by adding voice features to its service, he said.
