The Verge highlights 6 apps that show the promise of third-party apps on the watch. About Twitter:
“As you'd expect, many of the biggest social networks are ready with Watch apps on day one. Of those, Twitter's short-form updates seem to make the most sense for the Apple Watch — but it isn't Twitter's app itself that really stands out here. Rather, it's that Twitter is one of the social networks that soared thanks to the rise of smartphones. The Watch may not change that, but there's a chance that we'll see new networks build around it, the same way that Twitter, Snapchat, and Tinder have all built up around the smartphone.”
This is certainly on my mind as I write about and work on microblogging projects.
