The difference between Blogs and Groups,or Pages............

So far, from what I can tell,the main difference between Blogs,Groups and Pages is that:

BLOGS are, by & large, a sort of journal(daily, weekly or random entries),with the option to post a photo within the body of the text. Entries appear in the order in which they were submitted. with no consideration of content,context or author!

GROUPS are several to may individuals coming together, drawn by a common theme or philosophy in order to support that philosophy by sharing experiences,anecdotes,personal observations,etc. Groups often times contain either one large shared collection of member photos or allow for individual member's photo albums.

PAGES are less sophisticated than GROUPS,offering less input or participation to its members/subscribers. At the same time PAGES are more sophisticated than Blogs,offering greater input/participation for members/subscribers into the content of the page.
