Hello there Brakel2,
I'll provide the first answer to your question. I don't think, I know, as I am an active writer with HubPages being one of my avenues of communication and outreach with my writing.
So, my answer would be categorized as a: Yes! Some hubbers help others with issues, concerns, editing tips of their hubs and other uplifting measures as well. This is a good question to ask! As a frequent commentator on HubPages, I have helped others, with grace.
