Infinitely, yes. Tell me what's wrong and I'll fix it immediately. Tell me something is wrong by taking away 90% of my traffic but not giving me specifics and I am left having to guess. Sure Google may think this is a good and healthy thing anyway since it gets webmasters to improve sites but does it really improve sites? I would love to throw those resources towards content creation and visitor interaction instead of going on a Google goose hunt. Do my visitors enjoy me missing in action?
