I really agree with what you said:

experience is important and that we each share these experiences with the world. Mistakes and failed experiments that have already been tried simply creates unnecessary waste.

I think it's also very proactive to share these experiences to expedite the learning curve for noobies like myself.

I just found out about the HugelKultur Mounds and I am quite intrigued by it. I will follow up your how-to. Thank you for teaching me something new!
