Charlene Li's Blog reports:
Push exploded on the scene with Pointcast, landed faddishly on millions of desktops, and then just as quickly died away. (Of course, Push has been rehabilitated as RSS, but Push’s big problem -- content overload -- remains.)
Uh, content overload was NOT the reason Pointcast died. If anything, I'd argue the opposite, that Pointcast died because it had too little content. It was a very closed channel that tried to extract revenue from the transport mechanism. OTOH, RSS is winning because the transport mechanism is open and free... anyone can make content and anyone can subscribe.
I'd be interested to hear what Tony thinks.
