The word blog was derived from the combination of the word web and log.
Blog – a regular record of your thoughts, opinions, or experiences that you put on the internet for other people to read.
Blog – a website that contains online personal reflections, comments, and often hyperlinks, videos, and photographs provided by the writer.
Many people use blogs as they would a personal journal or diary. They use blogs as online journal or diary.
What is the difference or similarity between blogs or blogging and Facebook or posting in Facebook?
Facebook is a social networking platform that allows you to connect and share information with your friends, family, co-workers, and other acquaintances.
A blog is a form of journal on the Internet that allows you to write posts and entries about your life, hobbies, opinions, and other topics that interest you.
Although Facebook does not currently feature a blogging platform for its users, you can still share your blog entries on Facebook by posting blog links into your update status and using the Notes feature of Facebook.
Strictly speaking, there is a difference – posting online in a personal website is blogging and posting online on personal social media is Facebook (or Twitter or Instagram).
Loosely speaking, one can blog in websites and in Facebook. One can share the blogs in websites to Facebook and probably not share postings from Facebook to a website.
Websites have better archiving system of posts than Facebook.
Personally, I have blogs in WordPress.com and Google Sites. Oftentimes, I share my posts in WordPress.com and Google Sites to my Facebook accounts.
I also “blog” or post in Facebook using the “what’s on your mind”box; photo album, and Notes. I cannot share these posts in Facebook to my WordPress.com and Google Sites though.
