The article suggests Google could be a good partner for TW because of the infrastructure Google is building. I don't buy that. As far as I am aware, Time Warner Cable is the 2nd biggest cable co in the US(behind Comcast?). Why would they even need Google's infrastructure?
A spun-off merged AOL/MSN would be great for everyone, I reckon. It would allow them to "act like a startup", able to push forward technologies and be able to take more risks than your average startup (because they are being bankrolled by MS and TW).
And hopefully, it means I can dump ICQ for those few friends who haven't moved over to MSN Messenger yet!
