Don't stop with that blog. Follow the link to the article that inspired it.

The author has collected 54 super-spreader events, and presents common characteristics. I appreciated that he thought about what wasn't in his collection. His opinion is that these suggest that spread is by large droplets, at least for these events.
IMO, I think these events mostly have the same characteristic of being easily characterized. It is like looking at the danger of guns by looking only at mass shootings. As someone else here said, how are you going to know that you got infected by a nameless jogger that passed you on the street, you'll blame something else that fits an expected model. Other avenues such as movie theater or class attendance, he classes as quiet observation with few large droplets emitted. But I'd say the world has had few of those since the disease has spread, so it is early to dismiss those.
I don't think he mentioned the Huanan Seafood Wholesale Market in Wuhan. It appears to be a combination of interior & exterior (where items are sold), but the exterior is crowded & noisy. I can imagine there are cold areas in the market, not shown in the video.
A pair of interesting videos, from the same Indian tourist source: Wuhan 2020 (before COVID). A long tour of a seafood wet market is shown beginning at 1:20, but I can't confirm it is the infamous market where the disease spread early. And a post-lockdown Wuhan 2020, featuring mostly a Walmart-like food store.
