Websites as they existed in the 90s and 00s are no longer being created in any significant quantity. All of that creative energy still exists, but it's being more effectively siphoned off and monetized in the various walled gardens that make up the pastiche of the Internet that currently exists.
There are in fact a lot of really, really cool places still out there, but they've become occluded from search engine, and you can typically only find them through direct interaction with people. So the annoying answer is that you have to just keep doing what you're doing, and ask what's cool.
