Web Subscriber 5.1 has just been released on the app store. The new version comes with a new smart stream: Micro-Blogposts.
More and more people are starting to take their micro blogging out of social media silos and integrating tweet-like posts into their regular blogs or creating special micro blogging feeds (check out micro.blog for example).
If you follow blogs that are already containing posts like that (untitled posts with max. 280 characters), you can see all of these micro-blogposts in one in place in Web Subscriber under Discover > Micro-Blogpost.
