This is an interesting post I came across. While a lot of it American centred I think his speculation about the sort of thing that might become possible once iPad type devices, or even just iPads become very common intriguing.
It also indicates another use for posterous. When I come across something like this, all I have to do is tag it and send it to my posterous blog, and it will always be there for me to see again. Providing the link does not get taken down.
So to return to the question "why blog?" the usefullness of this particular post lies in its interest for me. Matters not whether anyone else is interested...
