Hi,
SCN is an utter disaster.
No. I don't agree to this at all. I started with SCN when I had done one implementation (with partner consultant) and knew about a fixed business scenario only. I came here for a purpose of learning and I could get the Topic leader badge in one year only. Today I know about several functionality and common issues.
That clearly reflects the significance of SCN and user participation. I'm still learning new scenarios, issues & their solutions and I can say, no training or lecture can provide the experience which SCN actually does!
