Great question, littlemarkiesmom!
I genuinely love using Hubpages due to its easy-to-manage design. I'm a fan of the fact that almost anyone could log on and start writing with confidence and not feel overwhelmed about creating and publishing their first hubs. I think that's what writing is all about - creating with confidence - and Hubpages allows you to do that more often than not.
In regards to other places which I like to write - if we're discussing free options in particular - you can't go past Ezine Articles as a great starting point. The waiting time to get a piece approved can be more painful than watching paint dry but that is offset by the sheer level of expose that your articles will receive if they make it through the review process successfully.
Another equal favourite is a article directory site know as SelfGrowth. I've always been big into helping others while simultaneously betting myself as a person. If what you like to write tends to take on more of an 'advice-giving' tone then this is a wonderful site to look toward.
I hope I've answered your question to a satisfactory level and I'm really pleased that you took the time to ask it.
