We've redesigned the look of streams that interleave multiple authors. This includes combined streams as well as the firehose and general thoughts tabs on the latest page.
Previously cards on these streams looked very different from what they did elsewhere because of the avatar and the use of the blue bar to indicate source (conflated with reposting).
Now cards have a consistent look.
With the new look, the stream title, author and avatar are now shown alongside the card.
If multiple cards in a row come from the same stream, we don't repeat the information.
On Safari (including iOS) the stream title, author and avatar are sticky so will follow as you scroll. This will work on other browsers as they roll out support for position: sticky.
