Big news in the media world is AOL’s acquisition of the Huffington Post for $315 million, a deal that will continue Arianna Huffington as news boss of AOL, which will integrate Huffington with Patch, its enormous investment in providing local news in underserved communities across the U.S. (if it’s operating in Arkansas now, I”m unaware.)

I’d be reluctant to hazard a guess on the short-term chances for profitability of an all-digital, all-niche-covered news platform. Sooner rather than later, however, the printing press seems certain to join the buggy whip in the museum of interesting relics of past times.
