Write for the Web : stop preconceived ideas !
Finally in web writing ideas are legion and persistent : one should write phrases of less than 15 words, simplify at most the message, avoid the use of negation and passive form, promote a subject-verb-complement structure, write in scan mode... Actually, as on paper support, writing must get as close as possible to the audience, to the subject, to the environment in which it takes place. A text for a Humanities revue or a site dedicated to Philosophy can't follow the same rules as a document conceived to promote a firm or commercial products.
The Eyetrack survey, carried out by the Poynter Institute in 2007, shows that netsurfers read thorougly online magazines, even more than they read written press. The legal blog of Maître Eolas, (
http://www.maitre-eolas.fr/ ), one of the most visited in France, is a perfect example. It demonstrates that long notes can be written and still develop the loyalty of a large community of readers.
