It also has to be a topic that advertisers would pay to target you with. You can't talk about something super obscure that advertisers don't care about - like steam engines.

Thanks for this!! Now my email is full of offers to buy historical steam engines, steam engine parts, and engineer hats. Amazon is even advertising a subscription for coal deliveries!

I've already bought two steam engines this morning. The ads were pretty convincing.

More likely, ads about games on steam.

Your inbox is now full of ads for model trains and hobby stores.

There are assuredly advertisers for steam-engine-adjacent products. Memorabilia, experiences/outings, conventions, models, books, artwork, games.
