Reddit comes to mind as an alternative (to Digg) that succeeded (by at least some definitions of the word). A massive amount of Reddit's early user growth came from a poorly-received redesign to Digg's home page. There are a lot of parallels to draw to the changes Musk has in mind for Twitter.

Difference here is that we don't see people leaving at massive scale. Maybe it's to early. Anyway, I think chances are 50-50 twitter succeeds in re-launch. I wouldn't be surprised of any outcome. But I would be surprised to see something else explodes in popularity just because it's twitter alternative.

The issue is that if you wait until people start leaving it's too late. The bet here (and IMO it's a fair one) is that Twitter will continue to degrade as a service and eventually people will start leaving. If your alternative is up and running by then you've got a chance of capturing users.

Who says people aren't already leaving?

Reddit also existed at the time and was a fairly mature product. It wasn't Reddit coming in after Digg, it was Reddit and Digg slugging it out in the market and Reddit coming out on top when Digg cratered.

Reddit had a clear killer feature with user created and moderated subreddits though, which Digg lacked.
