@EatPodcast Saw your conversation in chat earlier: In "Site Configuration" on Known set "Include permalinks" to "No" and you shouldn't get the repetitive Twitter card for things you send to twitter that are under the 140 character limit. If I recall, Brid.gy should still be able to find and backfeed comments based on the rel-me without needing the permalink in the tweet.

If you go over 140 characters, Known will automatically shorten the tweet and include the permalink so the reader can get the rest of the message. (I sometimes use this for longer than usual tweets in reply to people, like this one).

Generally you can include 117 characters + a URL and still always fit in under the 140 total.

If you manually include a URL, and the page has the correct meta data, the URL will turn into a Twitter card. If you include more than one URL, it's typically the last that will show the Twitter card metadata.

Hope this helps!
