I love the overwhelming theme of most answers here that hubpages provides much more and I agree 100% with that. Also, as a writer, this is the platform to get going on.
I am always thinking and reasearching as well knowing that I have followers that expect well written and interesting contents/hubs. I take pride in that.
I personally, for now, do not have a FB page. I may later, but not for now. I prefer my hub page and I just read last week that HP will have an iphone app! Woo hooo. I'll really be able to check my account as well.
I, too, love to hub hop, answer , ask and questions as well as checking out the forums, but wish I had more time in the day to do it while at my " 9 to 5" but I make the time and have established a writing routine with it when I get home. I try to get in at least an hour a day, but I am working on getting in a lot more!
