Sense: noun/1
Blog is the everyday term for a weblog — it is shorter, more casual, and used in virtually all modern contexts. An online journal stresses the personal-diary quality and is often used for private or semi-private writing platforms. A vlog (video blog) is a weblog whose primary content is video rather than written text. Website is the broadest term: every weblog is a website, but most websites are not weblogs — a weblog is defined by its regular, chronological, personal entries. For example, you might say 'I run a blog about cycling' (everyday), 'She keeps an online journal of her travels' (diary-like), 'He posts a vlog every Tuesday' (video), and 'The company's website has a news section' (general — not a weblog).
Etymology
The word weblog blends 'web' (from World Wide Web) and 'log' (a record or diary, as in a ship's log). It was coined in the late 1990s, and the shortened form blog soon became the dominant term in everyday use.
