Reddit has been ripe for disruption for years. It's just waiting on an inflection point and someone to take it behind the barn.
The network effects are too strong. Remember, the only reason Reddit "won" was because Digg destroyed itself with a radical upgrade that everyone hated. Reddit would have to do something similarly self-inflicted, and I can't even guess where people would go. Reddit was already an alternative to Digg -- what's the alternative to Reddit? I mean, it's certainly not Quora.

If it was deliberate I certainly can't tell, but one of the characteristics of Reddit is that it caused so many other little tiny internet forums to just wither away. Most were visually unappealing, running some ancient phpbb software or whatever, but there were so many like stars in the night sky. Now, if they're even still running, you look for the newest post, and it will say "November 2023". Hell, the only reason they are still running is that the credit card number on file paying for hosting doesn't expire until next year somehow. Reddit is a red tide algae choking out all life in the ocean, nothing else gets to exist anymore.
