If somebody asks me about, “what is the best platform for blogging between WordPress.com and Blogspot”, I‘ll said that it would be relative to person who use it. Relative? Like what? OK, I will classifying a blogger kinda type.
First, if you blogging with simple task, such write a post and give some picture illustration on it, I prefers to choose WordPress. Blogspot administration content is only write post, give it label, and publish it. Meanwhile, WordPress has more facilities in content management, like distinguish write page as a static page and post as looping page, sticky post, etc. WordPress also have a category for classifying post and tags to make it more classified.
Second, if you do some marketing activities, which is need popularity for your site, I choose WordPress (again). WordPress has a very great SEO feature because it’s easy for Google to index it, rather than Blogspot sites.
So, what your blogging purpose? 😉
