HDF is cool, no doubt; but I have mixed feelings about using some of these TLDs for important projects. I simply haven't decided how much to trust these small registries.
Awhile back I bought tra.gd when I thought I needed a short domain for something. If someone were to build a brand around a .gd domain, could Grenada change their rules to disallow international commercial usage? A more popular ccTLD example is .io.
