Why is Aragon special?

As a seasoned professional in the realm of cryptocurrency and finance, I'm intrigued by the buzz surrounding Aragon. Could you elaborate on what sets it apart from other decentralized autonomous organizations (DAOs)? Is it the innovative governance model that allows for seamless decision-making and community participation? Or perhaps the robust suite of tools and services it offers to support decentralized projects? I'm particularly interested in how Aragon is leveraging blockchain technology to revolutionize organizational structures and processes. Additionally, I'd like to understand the long-term vision and roadmap Aragon has for its ecosystem and how it aims to address challenges facing DAOs today.
