From the webpage:
Filter shows you the top stories from communities of Twitter users across a range of topics like climate change, bitcoin, and U.S. foreign policy.
With Filter, the only way you’ll miss something is if the entire community misses it too.
Following entire Twitter communities is a good idea but signing in with Twitter enables Filter to impersonate you.
This application will be able to:
- Read Tweets from your timeline.
- See who you follow, and follow new people.
- Update your profile.
- Post Tweets for you.
(emphasis added)
My complaint is general to all Sign in with Twitter applications and Filter is just an example I encountered this morning.
I can’t explore and report to you the features or shortcomings of Filter because I am happy with my current following list and have no desire to allow some unknown (read untrusted) third-party posting on my Twitter account.
If you encounter a review of Filter by someone who isn’t bothered by being randomly impersonated, send me a link. I would like to know more about the site.
Thanks!
