This is a sample page. It's different from a post because it remains fixed in one place and will be displayed in your site's navigation (in most themes). Most people start with an About page, which introduces them to potential site visitors. It could be something like this:
Hello! I'm a messenger by day, aspiring actor by night, and this is my blog. I live in Madrid, I have a great dog named Duque and I like piña coladas (and getting caught in a downpour)
…or something like that:
Company XYZ was founded in 1971 and has been offering quality “stuff” to the public ever since. Located in Madrid, XYZ employs over 2,000 people and does all kinds of amazing things for the Madrid community.
