Most of my hubs are directed at a wider audience on the internet. I believe that these are the hubs that will eventually earn money, so I spend most of my writing time on them.
However, I have written a some hubs just for fellow Hubbers. After we have been members of HubPages for a while, most of us feel like we are part of the HP community. Other Hubbers are our support system, providing most of the comments and feedback on the writing that we publish on HubPages; it's natural to want to speak to them through our writing. I think that the hubs written by HubPages members FOR HubPages writers are very important. These hubs are the way we learn to write better, get more traffic and make more money. They are also our way of sending out our thanks and appreciation to our followers and supporters.
