M.G. Siegler has a post describing what I thought Twitter’s new Fleets feature would be and goes into why it really doesn’t fit with Twitter in its current state. I agree with the assessment that this functionality just doesn’t make sense on this platform the way it does on Instagram.
I could see a world in which Fleets work, but as a different version of the product which was launched. No one is asking for my product ideas, so I’m going to give them. I would keep Fleets — which is a great name — simple: they’re tweets that go away after a set period of time. They reside not in some unnatural carousel at the top of the feed but in the feed itself. They’re highlighted in some way to showcase their impermanence.
