I just got a pretty good domain for SEO, it is subids.com.
What is surprising, is that I believe the domain was registered before, maybe not, but I remember trying to register it and I believe it was taken. Anyways it is now avalaible, and of course I registered it, it should get some nice organic traffic. You can see subids.com here. Just a very simple site, won’t ever be much to it, except for holding a good domain with some good content relevant to subids.
