Should probably put in a filter to let all the "Show HNs" live in their own section, otherwise a lot of users will simply enjoy the novelty of "new" things and Show HNs will dominate the homepage (although to me, it is a lot more fun than seeing the 800th boring link of how some mainstream company is doing something "amazing").
If you'd like more reassurance you could try these other editions of the above comment:
