If you read the published report, you'll see that only one of the issues are actually related to scalability in any way (and most newly created projects learned their lesson of not using auto-incrementing IDs for many reasons). The same goes for many companies, the downtime is not because of any scaling issues but rather maintenance, code deploys or other things where humans are involved.
So while the reward of you promoting your product on HN can be high, unless it's very specific and actually solves their need, it just looks spammy.
