I don't want to start a blog yet I would like to put articles online. I don't want to worry about things like a blogs name, layout or colors. But I would like to put an article somewhere and then share it on Reddit, LW, Facebook... and the site should preferably look reasonably professional (say, black on white, magazine like fonts etc.) so if you would write someone serious, say, Bryan Caplan, a comment saying "I disagree with some points in your article, here is my article to explain" the would not feel shamed linking to it in their own answer by the look of the site. Is there such a site that provides this?

EDIT: I would also like to know why so many people here seem to have blogs, personal websites, hosted under personal domains. What is the point? You want to keep the articles you write forever? I think if I write about something today 5 years later I will either be interested in something totally different or be embarrassed how ignorant I was.
