Nice.

Related, I noticed that sex.io showed up high in your list. For anyone considering registering the domain, think twice:

No .IO domain may be used, directly or indirectly, for any purpose that is sexual or pornographic or that is against the statutory laws of any Nation. In the event of NIC.IO being advised by any party that a specific site breaches this condition then NIC.IO reserves the right to immediately deactivate the offending registration. The applicant may seek the reinstatement of any suspended domain name by seeking a determination by an Arbitrator appointed by the World Intellectual Property organisation.

The above is from the nic.io allocation rules [1].
