Whoa....I am going to say that I am shocked at some of the comments here, so far.
It is ironic, for me, personally, since when I first jumped on board (literally, jumped) I joined via a friend's recommendation/invitation, so to speak. I hadn't read very much in terms of what HP is all about.
Thus, I had no idea for a while, that there was even a money-making opportunity involved. It was certainly nice to find this out, but obviously, not a reason for me joining. I had written for a local magazine for 5 years and simply tired of it entirely.
But, like most writers, I need to write as I need to breathe. Along came the HP opportunity and I went for it.
I, for one, love the friendship/fellow-writer relationships very much. In a little more than a year, I have established close bonds with quite a few very wonderful and intelligent individuals that I truly call "my friends," just as I do my long time friends in my real-life circle.
I am also one who enjoys the hubs in question here. I have discovered many new and talented writers and had the opportunity to follow their work, because of these hubs. It is a kind gesture by the writer to acknowledge, thank and/or "introduce" them to the Hub community. The writers who have written these hubs (myself included) ALSO write the productive, informative, informational and entertaining hubs that GOOGLE approves of. So,one or two hubs on a personal note, should not cause google any panic. However, I am sure that google,as well as HP can step in and put an end to anything they dislike, since they are the big kahunas. If, as some have said here, that "google and HP doesn't like the non-money-making hubs," I believe they should SAY so or take some sort of action.
Until and unless this occurs, I will continue to read the hubs of those writers I follow and enjoy reading. If the hub is a tribute, then I appreciate it with the sincerity it is written, and comment in like manner. "Who cares?" I do.
