I'm a big fan of writing conferences. Sure, some meet our personal budget and current needs better than others, and not everyone you encounter leaves you feeling all warm and fuzzy about your future potential, but if you go along with an open mind, the positives far outweigh any negatives.
If you know of a writing conference taking place this year, please share a link to its homepage in a comment. I'll upload it into the main post here.
