After spending the better part of the last month working on it, I finally decided to pull the trigger and publish my Django Stripe Integration Guide.
After publishing, I posted it on /r/django and made #1 for most of a day. All of the feedback has been super positive, which helps me feel better about all the effort that I put into making it.
And with basically zero other (successful... damn you Hacker News!) promotion it's also getting picked up in other places, including on someone's Google Assistant home screen, as well as getting Tweeted by @fullstackpython on Twitter (which has 50k followers). This re-affirms my content strategy of "make above and beyond content, and people will naturally share it".
I haven't seen a super-meaningful uptick in sign ups or sales yet, but hopefully that will come later as more people find the guide and then (eventually) convert to customers.
