I once heard e-mail described as "the ultimate push technology", and for a while, I agreed… Until I started using RSS.
The other day, someone I was talking to said that RSS wouldn’t work in a given scenario because it was a pull technology.
I have to disagree with that previous statement. (Not the applicability issue, but that RSS is a pull technology…)
I can see that behind the scenes RSS is a pull technology, as a client needs to go out and grab the content.
However, in usage RSS is just as much a push technology as e-mail. (At least the way I use it, via Google Reader…) When I fire up my RSS reader, all the stuff that has been pushed to me is waiting right there. Effectively, I don’t see how that is any different than having Outlook call the Exchange server.
What do you think?
