According to Wikipedia (as of 2/5/18): Blogger is a blog-publishing service that allows multi-user blogs with time-stamped entries. It was developed by Pyra Labs, which was bought by Google in 2003. Generally, the blogs are hosted by Google at a subdomain of blogspot.com. Blogs can also be hosted in the registered custom domain of the blogger (like www.example.com). A user can have up to 100 blogs per account. Up until May 1, 2010, Blogger allowed users to publish blogs on other hosts, via FTP . All such blogs had (or still have) to be moved to Google’s own servers, with domains other than blogspot.com allowed via custom URLs. Unlike WordPress.com, Blogger allows its users to use their own domain free of charge, while WordPress.com charges around $13 to use a custom domain. Blogger cannot be installed on a web server. One has to use DNS facilities to redirect a custom URL to a blogspot domain. Blogger is available in over 40 languages . Blogger is developed by Pyra Labs, which was acquired by Google in 2003.

From the website: Comment Rating makes “user moderated content” possible. This plugin automatically embeds clickable images in comments using simple light-weight AJAX javascript (not heavy-weight jQuery) to allow visitors rate comments in Like vs. Dislike fashion. The votes are displayed along with the comments in either two numbers, one combined, or both. Once the user ratings are in place, the comments can be displayed and styled accordingly. Poorly rated comments (too many Dislikes, not enough Likes) can be hidden in a click-to-see link, just like those on Digg. Highly-rated comments (a lot Likes and few Dislikes) can be highlighted. Hotly-debated comments (many Likes and Dislikes) can also be highlighted to draw more attention, to fan more votes and comments. The thresholds for all three types of comments are configurable. So are the styling. Styling can be done with background color, fonts, etc. on the comment as well as the entire comment box. This plugin allows using Wordpress as a general CMS in a Web 2.0 fashion. User generated content can be voted by other users. Example website is Caption Wit. Followings are a few example screen shots. Update : Comment Rating has been discontinued.
