From a speculative standpoint, the best thing about stickers is that early buyers can't dump them, so it will never become a pump & dump ponzi scheme like Friendtech shares. As an early buyer, you will continuously enjoy a share of the revenue from future sales forever.
This might be the healthiest model I've ever seen. Ofc, you won't make a 1000x return on it, but this is not the point of it. It's just a totally sustainable way to monetize creator content.

I see a lot of potential in this; however, it would be great if it could somehow fulfill the role of an "upvote" at the protocol level. Without this, the general statistics of a given Lens profile could become significantly skewed, especially if Orb gains a larger market share among Lens apps over time. "Upvote" should still be a globally measurable & visible metric that you can give and receive in all Lens apps. Of course, this is just my opinion—ultimately, it's up to the app developers and the market to decide.
