I'm thinking of starting a newsletter on Indie hacker guide -- new tools, products, insights every week. Thinking of using this community, indie hacker, Twitter to curate the resources and send it every week for generic or specific topics.
Please let me know what do you think or if you've any experience with something similar
I think that the best way to actually validate an idea is to make a small landing page or a MVN (minimumal viable nothing). On a landing page you can describe your product in a quick and efficiënt way.
An MVN however will be a bit better. Showcase your idea with a landing page that offers textual and visual display. Do leave a message that the product is not built yet and that you need feedback. It will make it easier for everyone to understand what you would like to offer. By everyone, I mean everyone (Indiehackers, colleagues, family, friends, Twitter, Reddit etc.
Goodluck :)
