...It's a laundry list, but are these even worth investing in? Only one I've seen a real use of is .io

I know the requirements are long, and some just aren't being offered right now? I'm just surprised that other countries haven't tried to extend their tld to entrepreneurs?

Just wanted to get some discussion on this, see what you guys have to say about it. Even more, if you have ever found any cleverly-used TLDs, please share :)
