I think that's right in the first order, but the second order is that journalists and gadget enthusiasts do, and they may write about your product. That happened to me with my Show HN post on here.

Agreed. I think it's worth posting on it but the right attitude is just treat it as any other outlet to post your product. Don't fret too much about it or spend too much time prepping and trying to game the timing.

When I've posted projects on there, I found so many bots commenting and then later got several emails from people wanting to "help" me with upvoting for a fee, it made me realize how fake it was.
