blogs or message boards

I still am not sure of what a blog is, and how and why it would differ from a message board.
______________________________________________
There can be similarities between a blog and a message board.
Both can build communities of people with similar interests
or people who are trying to solve similar problems.

I think a blog is where one person puts up some information, ideas or opinions and others comment on that information or those, ideas and opinions. One person (or sometimes a group of people) chooses the topics. A blog is a reflection of experiences and thoughts of one person (or small group).

A message board is a place where many people share information, ideas or opinions. It is not the reflection of one person (or small group) but of a wider community of people.

On a message board - everybody is invited to share equally.
On a blog - I write stuff and you comment or not as you wish.

Here is an article on this topic by CommonCraft:

It is a bit of a long article. You may find the chart helpful.

Or here is a shorter version:

• A blog post says “Here it is, dig it”
• A message board post says “your turn”

• A blog is my back yard
• A message board is a park

• When things go quiet on a blog, the onus is on one person
• When things go quite on a message board, the onus is on everyone
