My take: I am an MVP and I couldn't really care much for that. What matters for me is to meet and collaborate with individuals who are equally passionate and enthusiastic about technology, regardless of status. We're in this community to learn and share and accelerate our absorption of knowledge. I'd say give little weightage to the signature of anybody and just concentrate on their content and judge for yourselves if you'd want to listen and follow their advice. Those not worth it, should therefore, be ignored - why waste time lamenting over them?
