TweetScreenr (https://tweetscreenr.com/) goes through your Twitter timeline (and your twitter lists) and fetches only those tweets with an external link. TweetScreenr grew out of my frustration with Twitter. I found myself relying on Twitter to follow a particular research community, but realized that I do not care about the actual tweets/threads - all I wanted was the link to the underlying paper/article. I also did not like how often I got sucked into reading an opinion thread (usually political), and I walk away 30 minutes later thinking to myself "do people really believe those things?". All I want out of Twitter is some sort of personalized hacker news, and this is my attempt at creating it.

Apart from viewing the external links/articles on the TweetScreenr web app, you can optionally receive a daily/weekly email digest or read them on an RSS reader. The premium version ($1 a month) supports blocking specific domains and accounts, and also supports Twitter Lists.
