Answer 1

Captains in old types used to write down their experiences on board. They would write the state of the ship, the crew, etc. They would write when they saw land, stopped for supplies, or did anything else of note. This was known as a captain's log.

On the internet a blog (web log) serves to record the interesting experiences one has in day to day life. At a technical level, a blog is just a regular website.
