Somebody should change that for incubators and YC, being the most forward thinking and advanced one, should be the first to try:
IDEABOLT: Apply to next HN with non-profit startup to care for kids (preschool 2-5) of HN batchmates onsite at YC (with its blessing, taking over a large room or some converted space nearby). Not only this would increase the pool of applicants greatly (really?) it boosts the coolness of HN close to \infty.
The service will be free (9-5) so how to make money? Investigate innovative preschool learning methods using the kids (of course, with parents permission). This target group is perhaps the least served child demographic (no good solutions for something as mundane as poop/feed tracking, https://news.ycombinator.com/item?id=10075191), except mundane stuff like diapers and bottles).

Graham treated Adam like a little founder, interested in his interests."
I would have expected this! OK, Add to the idea to mine kids for ideas, Big fashion.
