Content blogs, and reblogging or syndicate blogs, are receiving a fair bit of discussion among various business blog commentators.
Darren Rowse at Pro Blogger presented the idea of the blog types. Paul Short at BlogLogic has picked up the theme. Discussion of those two posts continued at Chrispian Burk's Nothing To Say blog.
In general, the discussion revolves around whether to write original content or to find other blog posts and add your own comments on them.
Most bloggers use both techniques at one time or another. Many blogs will include more reblogging and commenting of other blog posts. Other blogs will lean more heavily on original columns, how to articles, and opinion pieces.
Like most bloggers, I provide both types of posts.
In general, my most popular and most heavily commented posts are my original content columns. Since I try to provide helpful information on SEO, marketing, business management, business blogging, and public relations, much of what I write is my own creation.
On the other hand, I also write about business and blogging topics that are being discussed in the blogosphere. That is what I am doing today, as a matter of fact.
This is a reblogging post on reblogging and original content.
Because there is really very little under the Sun that is truly new or unique, all posts are reblogs in the strictest sense.
I would say that the best definition of reblogging or syndicate content would be if a post comments on another blogger's post, information, or ideas then it's a reblogging or syndicate blog post.
If the material is written from original research or knowledge not currently discussed in the blogging community, then it's original content.
Of course, many variations and exceptions are likely to be found.
In fact, I believe there are many more blogging categories than simply the two currently under discussion.
In any case, write the blog posts with which you are most comfortable.
Write the posts that provide the most value and information to your readers.
If you keep your readers in mind, you won't ever go wrong.
