Diferencia entre un post y un artículo

Una cita interesante, que tomé de aquí:

What is the difference between an “article” and a “blog entry”? A blog entry something that I think up one day and write about in probably under an hour. An article is something that I think about for days, weeks, or years, and generally try to research. An article is my best considered opinion on a subject after scrutiny; a blog is just my opinion one day. Consequently, I write the word blog on my blog entries, and give an article identifier to each article I write, so it will be easy for you to tell the difference. (Alistair Cockburn)
