I was recently asked for great writing resources for a person who is writing for the web. Right off the top of my head, I recommended E-Write’s free e-newsletter (ewriteonline.com) and Elements of Style by Strunk and White.
I have previously posted about some great advice from Jakob Nielsen: http://jakprpro.wordpress.com/2008/06/18/writing-for-print-versus-online/ and also Gerry McGovern’s 6 Cs for great content: http://jakprpro.wordpress.com/2008/06/27/killer-web-content/
What is you favorite writing resource? Share it here.
