Twitter, tech industry
Twitter wants to implement a feature to limit who can reply to your tweets. Sounds good in theory, if not for quote and screenshot retweets. Which Twitter is aware of, but it doesn't change anything.
Also remember that disastrously ugly "little t" beta that was circulating months ago? Yeah, they're still thinking about that.
Frankly, Twitter is missing the obvious problem that has no solution but it's own non-existence - Twitter's volume is unmanageable. You can't realistically curate and moderate that without dismantling it.
