✍ Can you write about Go?

As you know, we're always keen to link to good Go articles and we want to take a step further in actively encouraging the production of new tutorials, guides, tips, etc. so we both want to launch our own Go article site and encourage people to post more on their existing blogs, etc.

If you are a blogger or author, and can (or do) write about all things Go, please get in touch at go@cooperpress.com. You must:

  • Send us links to existing blog posts or articles you've written.
  • Have experience writing on technical topics.
  • Be prepared to write for our new site or have an existing blog of your own.
  • Have strong English skills (though we can edit.)
  • Optionally.. you can immediately pitch us on any ideas you have.

💰 This is a paid opportunity (the rate for original articles will depend on format, topic, etc. but think in the range of $100~$600 depending on what it is.) Also, we can't take on everyone (so those samples are really important) but if you have writer's block or are short of ideas, no problem, we'll be very happy to feed you prompts to get you started 😄
