The idea of collaborating based on common interests and ideas sounds promising to me, even mouth-watering, yeah, but I haven't explored any of this yet. I'd like to learn how it works and how it doesn't work out. What are the obsticles? How common is it? Would be phenomenal if fellow aspiring and professional writers cared to share their real-life experiences on the matter. Please be brutally honest, it's especially important to understand what kind of writers are best suited for collaborative work. Thank you!
