I would want to see how they go about not only building the software, but marketing it. I am sure that probably won't be part of the 24 hour project, but it would be interesting to see/hear how they plan to get the word out (aside from this obvious method of taking part in a huge live-stream event)
One of the goals of the challenge is to launch on Product Hunt, Reddit, IH, dev.to :), and any other places you can think of to get the word out to the right audience.
We have a Telegram community and are sharing a lot of best practices and hope to carry on helping after the challenge with marketing, validation, and monetization.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
