Cross-posted from my dayjob blog.
A couple of years ago, I wrote an article for Intercom magazine called Ten Tips for Writing Whitepapers (PDF). I just had a quick glance through it, and I think every thing’s still relevant.
Regardless, my technical writer brother sent me two other articles on writing whitepapers. There’s 10 tips for writing compelling white papers and How to Write a White Paper – A White Paper on White Papers. The latter requires registration, and apparently the registrations get vetted before you receive their article. In light of the fact that I used my spam account at Capulet (a company that, you know, writes whitepapers), I’m unlikely to receive a copy. If anybody else registers and gets a copy, send it on to me, would you?

I’ll send it to you when I receive it. I requested it because I have been working on a whitepaper on how to write whitepapers. Perhaps this will encourage me to finish it. Unfortunately, paying work so often gets in the way! 🙂
Aww, I hate it when companies use audio on their home page. Shame on Stelzner Consulting.
Anyways, I’ve signed up for it, and since my company website doesn’t mention the first darn thing about offering copywriting services, perhaps I’ll get lucky.
