Buffer is one of those apps that can really help you keep on top of your social media activity. I recommend it regularly to businesses and bloggers, as it allows them to set up a schedule for when they want to tweet or post, and then just add new shares to their queue.
But when it comes to engaging with people and influencers on Twitter, Buffer has never been a good choice. You'd have to know the Twitter handle of someone in order to mention them in a Tweet shared via Buffer.
Now, however, Buffer on the web and on mobile offers you the ability to begin typing in someone's name or handle, and let Buffer autocomplete their Twitter handle for your selection. Simply type the @ symbol and a few letters to begin seeing suggestions.
