Social networking uses the power of Internet technology to connect friends and like-minded people. Sites like MySpace and Facebook allow users to build personal profiles and interact in new ways.

I woner if I could replace "Social networking" in the above with "Social network." If yes, does it make a difference in meaning? Thanks.

Not in the singular; you aren't describing a single network but the whole mess of 'em. "Social networks use the power..." sounds fine to me. And avoids the appalling verbification of "network," although I suppose it's something we have resigned ourselves to by now.

Thanks, Delmobile.

Got it.
