Estimated "True" Rating

Do you believe only high rated chess players are worthy of listening to?

All chess players are worthy of listening to but the limited information in the forum should be relevant. Imagine if your driving licence had irrelevant information such as the size of your feet meaning you had to go home a get picture id every time your driving licence is required?

What makes moves/location or date joined more important than one's rating that they are included while rating is not? Why then don’t we have size of feet or whether you had cereals or toast in the morning, as forum information?
