No, I don't think it's advertising. So no objection to including them per sé. It's really a question of getting people to share the information, and making it easy to navigate the various different arcades. When they are all listed with their information on one page, it's simple to scroll down. Ideally we should have an interactive tool, that you can re-order the arcades/brokers/software etc by one of any number of criteria. But in the meantime you just need to be aware of the limitations of what can be achieved by the Traderpedia.
