SankeyMATIC (BETA): A Sankey diagram builder for everyone AEA365 Hello, my name is Jayne Corso and I am the Community Manager for AEA. As a community manager, I create weekly posts for AEA’s Facebook and Twitter pages. Although you can share similar content on Facebook and Twitter, your approach should be unique for each channel. I have put together a few tips for composing text for both Facebook and Twitter. Facebook: Hot Tip: Keep it to 80 characters The Facebook character limit is technically 63,206; however, when posting on Facebook, you should try to keep your text within 80 characters. Hot Tip: Don’t just post a link Facebook is a great channel for sharing blog posts or linking to external content, but don’t just post the link. Hot Tip: Use images Facebook posts that use images receive more engagement than posts without images. Twitter: Hot Tip: Keep it simple Twitter has a character limit of 140, but studies have shown that posts that are 120-130 in length receive better engagement. Hot Tip: Grammar is still important Good luck crafting your posts!

" C'est une triste chose de penser que la nature parle et que le genre humain n'écoute pas " Victor Hugo Une catastrophe naturelle ne dépend pas de l'intervention de l'homme.
