Steve Beard, an edublogger, reflects about his attitude towards sharing vis-a-vis blogging:
Whenever someone tells me something interesting, something that I think the wider audience would like to hear about I say ‘have you put it on your blog?’. This seems strange as previous to me maintaining my blog I maintained part of a website, but I never said to people ‘have you put it on your website?’. Is it the medium that has made the difference or my philosophy that we should share and publish more and more.
The medium isn't the message, unlike what Marshall McLuhan says. But the medium surely makes a difference.
