Example: https://www.brid.gy/comment/twitter/kevinmarks/511308494947876864/511385288518557696

Should wait for snarfed/bridgy#287 to be completed.

Ping @pfefferle here, this would probably make sense still as well, right? I'm a bit out of the loop right now, so just double checking – not trying to get you to add them :) I can do that the next time I get around to check on these.

These should certainly help improve the presentation quality of stuff pinged to my endpoint.

Sure, I think brad.gy is one of the most used tools. Perhaps we should add several ones, perhaps a 'like' and a 're-post'...
