I collect at a rate that far exceeds our production capacity to develop and have a nice collection stored at a relevant domain. It's not advertised or used, just an alternate management technique.

I own somewhere around 600 domains, with only 20% in any type of active state.

I think there are about 200 on the site, thinkfur.com and skycaver.com are probably my favorites that don't have a planned use yet. Awakera.com is pretty solid too.
