Built with vanilla HTML, CSS & JS. No frameworks

That's something I haven't seen in a while!

Neat! Do you have a simple TLDR for how it was done? I'm assuming HTML canvas but would be curious to hear the mathematics behind it

At my old company we did some guerilla marketing on Reddit and got a post go mega viral (front page for 3 days) 15k+ upvotes.

For us it was a bit different because we were doing robotic F&B so people could come to our restaurant to see the place from Reddit IRL.

I would target memes in niche dev communities if you want direct outreach. Like if you're looking for people to test your product you'd have more luck on a 100 upvote post in some obscure deeptech subreddit then you would if your post got 10k upvotes on r/funny.

Sorry for any grammar mistakes - writing this on the rush hour train :)
