The great thing about thought bubble is the oppertunity to meet the guests from the comic industry as they're an abundence of knowledge about how to break into it. If you're looking to get into comics Thought Bubble is a valuble experience as you can network incredibly easily with guests, one year they even had a memeber of Marvel's Editorial team doing portfolio veiwing. Ofcourse there are also many smaller publishers who attened. In industries as small as video games and comics it's these small events that are truly the best way to start networking, obviously when speaking to people the correct etiquette is always required but I strongly recommend those looking at getting into comics go to thought bubble. The convetion is open to the public but each year it gets bigger and bigger so be sure to be prepared!
