>It's probably full of stuff no advertiser cares about, like your love of old British railway cars
As a railway enthusiast myself, I would say that's actually an opportunity for very effective targeted marketing:
* There are loads of specialized reference and historic books and video on the subject.
* The crossover interest to model railways, a hobby involving many high-margin purchases, is very high.
* Many enthusiasts literally plan their vacations around preservation railways and museums. Everyone from the tourist-railpass sellers to full-fledged package tour operators should be targeting them.
If that interest is not well advertised to, it's either because they're doing a poor job identifying the interest and routing it to advertisers, or they've done a terrible job of fostering ad buyers in those verticals.
While, yes, it's theoretically possible, there must exist some company paying Twitter to sell one of those products, and who wants it specifically targeted to the group.
