Blogger

Blogger is, as the name suggests, a blogging service. It is also the most popular one in the entire planet.

The site first launched in 1999, funnily. In 2003, Google bought the site out, increasing their profits significantly.

As with several other services owned by Google, it is blocked by those goddamn repressive countries. This is somehow less surprising than one would like to think.

It is currently the 5th most visited site.
