I wonder whether these guys will end up working on increased integration with other acquisitions (e.g., Instagram, assuming that all goes well with the antitrust investigation with the FTC), or potentially even on other other services themselves? I'm looking forward to seeing Facebook's plans with photo sharing -- especially after Facebook's post earlier[1] highlighting the increased prominence of photos in their mobile app.
