Here’s the thing: I had zero idea how to use Twitter. Wasn’t it something just like a Facebook status, except with a character limit? Half-way through the conference, I realized everyone was including what looked like keywords in their tweets – and always after that pound symbol (yes, ladies and gents: it was the hashtag). Clueless. Or should I say: #Clueless. I spent most of my efforts that year crafting and posting thoughtful blog posts at the end of each day, occasionally sharing them on Twitter.
