I made this for my recent presentation about web writing. A lot of it is not new to expert webessionals like you, but to my audience on the day most of it was new. Might even have been interesting. I’m putting it here so I don’t mislay it.

Print writing	Web writing
Adverts come first	Adverts come second
The writer is the expert	The readers are expert
Each article exists in its own right, separated	Each article is part of a wider whole
Readers may respond and might get their response published	Readers expect to be able to respond, and their responses to appear instantly
Readers expect to pay	Readers expect not to pay
Articles are hard to share	Articles are trivially easy to share
Readers can’t easily respond elsewhere	They can
Prose is best	Notes are best
