The reason discovery is down isn't because they're hard to find, it's because there's much more interesting "entertainment" on the web these days, such as Youtube, Netflix, Reddit, and other time sinks. Back in the days, Flash games and geocities were the only forms of entertainment, which is why they were so big. Nowadays, we've got amazing free content and games everywhere, which is why this kind of entertainment isn't as sought after anymore. It's not lack of discovery, it's lack of demand.
