for eavesdropping on a conversation that they weren’t a part of
Why Twitter’s Dying (And What You Can Learn From It)
umair haque

Clearly, abusive communication (especially unchecked) will poison the well. However, I’ve often thought that the Public feed from Old Twitter was one of the best parts of the service. Now, akin to Facebook, you only see content from those that you follow; or if you feel like exploring their curated / trending stuff, which I’m guessing doesn’t get much attention from users.

Basically, I think the whole eavesdropping is something Twitter got rid of early on and is why it’s losing traction, except in circumstances where a hashtag trends enough to appear in your feed.
