I use WordPress from past couple of years and I am very fascinated with this platform. I would recommend it to others as well because it has got everything that you will need to run a successful blog. You can choose from thousands of cool WordPress themes to provide your blog with unique and exquisite look.
I am using Weebly. It may not be as popular as Blogger and WordPress. So far, it works good. User friendly, although not as advance as other platforms. Because my blog is very new, I am OK with simple interface.
Please take a look at my Weebly blog here at One Sleepy Mommy and tell me what you think :)
