We use Buffer to curate blog posts or prepare individual elements for our content plan. The add-on is very useful and helpful for this. But of course it is only interesting for Buffer users.

I love this extension to share m publications on social medias

This app is great.

I use buffer on a regular basis for our nonprofit NGO to post contents from our webpage to Twitter and Facebook.
Works fast, reliable and rock solid. The only drawback I found so far is that on Facebook, the author always is "buffer" and not me. But maybe I just haven't found the right button yet ...
