The ONLY reason I’m using Twitter (alongside other social networks) is the ability to continue browsing tweets from where I left off last time.
This is the ability that makes it useful as a universal newsfeed (Other social media are not good for this). As Leo Laporte put it recently in the This Week In Tech podcast, Twitter kind-of killed RSS as it is doing almost the same thing just better. This may not be the only thing people are using Twitter for, but I think it’s one of the top 3.
This phenomenon makes it especially strange that in the 10 years of Twitter’s existence, they haven’t been able to further exploit this ability. It is not only unable to make me use my feed in a cross-device manner properly (my Google search “How to use twitter on multiple devices in a way that they remember where I left off?” has just provided zero meaningful results), but when I upgrade the Twitter app on my phone and launch it next time, it opens showing the top of my feed. Very annoying.
If there are UX researchers at Twitter, they could take a look at this.
