Hope you're getting your submissions ready since the deadline is on Monday December 10th! We'll be meeting later next week to pick the people who are offered slots on the Saturday, so we won't be able to accept late submissions. We may combine people on a panel, i.e. don't worry if you don't have 45 minutes worth to talk about, and if you want to be part of a panel, put that in your submission. Make sure you put enough detail in your submission; you need to show us you've thought about the subject you want to talk about and can come up with something interesting for people to listen to. Corporate sales pitches are right out; the theme of this conference is personal and educational blogging and social media.
If you want some ideas, check out the ideas page. Or the call for submissions page.
