Apart from Google+, I also use a few other channels to source and sink curated information to/from the www. The one that's surpassed my expectations by far and could potentially replace G+ for me is Telegram, with a little tweak though.
Telegram launched https://telegra.ph/ not too long ago as a mechanism for publishing content that can then easily be embedded into chats, groups or channels.

Telegra.ph is a minimalist publishing tool that allows you to create richly formatted posts and push them to the Web in just a click. Telegraph posts also get beautiful Instant View pages on Telegram.
