Yes, it’s another 12 Apps of Christmas post. Not to show favouritism I’m also taking part in the RUL 12 Apps of Christmas and there’s still time to sign up for this one too.
Sli.do looks brilliant. It’s a quiz with a built in back channel for questions. So it’s better than other back channels I’ve used in the past as questions can be anonymous (but don’t have to be) and others can vote on questions that they want asking, all at the same time as running a poll.
