(and many more)
I have collected over ~60 domain names over the years. And while I really hate traditional domain parking sites, I also did not like the fact that my domains were sitting there idle, doing nothing.
For those interested, I scratched my own itch by building Newsy
https://www.newsy.co
It turns your un-used domain names into an automated content aggregator (i.e. Reddit clone).
I connect my domain (HTTPS enabled), I give a few keywords that are relevant to the domain name or idea that I have which I would eventually want to use with the domain and Newsy finds and displays contents based on those (e.g. News, Videos etc).
We've built various features like comments, membership, votes, automated newsletters, integration with Twitter that help your site build traffic over time.
A few examples

Would love for anyone else to give it a try.
