It seemed so effortless, but when I tried to do it during that first conference, it was frantic - simultaneously sharing tidbits as I tried to listen and absorb new knowledge, take photos, look up speakers' usernames and relevant hashtags, and edit my final message to fit the available 140 characters (at the time).
Since then, I've live-tweeted a few more conferences, and have figured out a workflow to engage folks online without being glued to your phone and losing the value of the in-person presentation.
(Spoiler alert: It's all about the pre-conference prep!)
