When you write a piece of fan fiction, that's writing. It asks nothing of the reader accept to take it in and (hopefully?) create a best-selling vampire franchise out of it. When you write the email that invites people to your annual Harry Potter marathon, that's copywriting. Copywriting is used whenever you want someone to take action.

• RSVP for your Texas BBQ (even though you live in Minnesota)
• Sign up for your mailing list
• Use your open source project

So... when you want someone to:

• Read your docs
• Use your OSS boilerplate
• Come to your webinar
• Download the latest release
• Take your course

You need copywriting.

Have a lovely night,
