I've never heard of an online convention before. So when I found out that an upcoming writer's convention would be held entirely online instead of at a convention center or hotel (like they usually are), my interest was definitely piqued. WriteOnCon is a convention specifically geared toward kidlit writers, but a quick glance at the first day's schedule reveals quite a few topics that could apply to writers of many genres. Best of all, it's FREE! If you're a children's or young adult fiction writer, or just a writer in general, check it out!
Special thanks go to Karly Kirkpatrick and her blog, without which I would never have stumbled upon this gem.
