Many cool worlds are unknown and not easy to find. Here are some suggestions to change this:

1) Genesis Plaza presence

At the Genesis Plaza Landing zone, there are already "Best Rated", "Events Explorer" and "Find People". Why not add a "Random World" section, where random worlds or POIs are showcased? In this way, visitors could be directed to worlds or parcels that they would otherwise only find by chance or with ABC Tours.

2) Buttons

It would be also cool to have a button there or even at the Decentraland Marketplace next to "Land" which links direct to the worlds overview page. Many people do not know this URL: https://decentraland.org/places/worlds/

3) Subdomain

I'd even suggest a subdomain "worlds.decentraland.org" with the same URL redirect for easier accessibility. It's also easier to remember than a long URL

4) Tags

You can select a category for a world in the Creator Hub, but with custom tags it may be easier to find a specific world. So let the creator define custom tags which can be found by searching on the worlds overview page.

Just some brain farts from by side.
