I imagine a lot of these were purchased as "Hey! There's a .museum top-level domain! Let's buy it! ...You know, we should probably write this down somewhere."
This is similar to .travel top-level domain. Someone thought it was a good idea, just like .museum.
Since 2006, the travel.travel registry has sold 200,000 .travel domains. I am a heavy user of travel sites (Expedia, Hipmunk, hotel sites, etc). I have never, in the course of my online usage, ever run into a .travel site.
This is why gTLDs are likely to fail. At least for users and for purchasers of subdomains, not necessarily for the registrars.
