tldr of the tldr for those who don't want to click out:
- Devs do hate advertising. The level is extreme, unreasonable even.
- Devs love swag. Unreasonably so.
- Devs appreciate good tutorials and blogs.
- Devs only really trust other devs.
- Say what you don’t do to build trust.
- Devs use a lot of ad blocks.
- Podcast ads work.
- Say what you do, let me try, wait for me to reach out.
- Devs think marketing == promotion and ads.
That said it could still land a message/spark interest.
And perhaps if it is worth investing your time in, you'll hear about it again, hopefully from a source you trust.
