I have a 6 year old that can navigate an interface with links. He can also read. However, his critical thinking ability is still being formed, as is his frame of reference of the world. I'd prefer to not give him access to an unfiltered firehose just yet. I don't know how old you are, but when I grew up, the web was in its infancy, and you could take your time to process the information available, and everyone wasn't yet posting about everything they may or may not have a qualified opinion on. Times have changed, unfortunately, and we have to adapt with them.
