Breaking the silence by posting something unsubstantive is the worst thing you can do. Threads are sensitive to initial conditions. Please don't do that again.

It's quite normal for a thread to get upvoted but not get comments for quite a while. If that means people are reading and digesting the article, that's great. We want reflective comments, not reflexive ones (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sor...) and those take time.
