Difference between blogs and forum?

Any one know the difference between blogs and forums. In my point of view blogs related to single user and forums related to multiple user........is it corrent

FSX, what about blogs that have comments? Then their more alike; Someone says something, and then other people respond.

There is also a semantic and structural difference. A blog post is essentially an article that has been published and stands on its own merit. Any comments will (or should) relate directly to that article and are normally of far lesser importance. With a forum the topic post may start a thread but is not of any greater importance than the replies that follow. In fact, it may be of less importance if its a question and all the useful information is contained in the replies. As matt1298 indicated, with a forum its all about the conversation, with a blogg, its all about the article.

what i would do is go to ask.com and ask that question... and get a simple answer... or waste more time searching threw googles billion pages..

Q

*  A blog is owned by just one person, or a small group of people. The blog owner chooses the topics of entries on the blog, and controls who can read and comment on these entries. Although people can comment on entries, this is not the main focus of the blog, and it is possible for the blog owner to create private entries which cannot be viewed by anyone else. Because the blog owner has complete control over what appears on their blog, the blog can form a personalised reflection of the work, interests and ideas of one individual.
   
* Forums are not controlled by one person - instead, any member of the forum can start a topic for discussion. Forums rely on responses from the community to initial posts in order to form a discussion, reflecting the interests of the group rather than of an individual.

Q

Some people do not seem to be able to get their heads around the difference between blogs and discussion forums. To my mind, although at a surface level they have some similarities - at a deeper level they are fundamentally different.

There are two dimensions to their differences - the first the psychological dimension and the second the technology dimension. One of the major psychological differences is that you own your weblog - it is YOURS - and it represents a history of YOUR thinking - so you take pride in its ownership - something that does not make a lot of sense in a discussion forum.

On the technology front - Ray Ozzie sums up one of the major differences:

    In traditional discussion, topics and their responses are contained and organized within a centralized database. The relationship between topics and responses is generally maintained in a manner specific to the nature of the database - that is, in newsgroups the messages might be related by Message-ID hyperlinks or crudely by title, in Notes they are related by the $REF hyperlink, and so on. Summary-level "views" are generated through database queries. And that has been the general architectural design pattern of public discussions for quite some time.

    But blogs accomplish public discussion through a far different architectural design pattern. In the Well's terminology, taken to its extreme, you own your own words. If someone on a blog "posts a topic", others can respond, but generally do so in their own blogs, hyperlinked back to the topic's permalink. This goes on and on, back and forth. In essence, it's the same hyperlinking mechanism as the traditional discussion design pattern, except that the topics and responses are spread out all over the Web. And the reason that it "solves" the signal:noise problem is that nobody bothers to link to the "flamers" or "spammers", and thus they remain out of the loop, or form their own loops away from the mainstream discussion. A pure architectural solution to a nagging social issue that crops up online.

I'm tempted to retool PunBB's look and use it for a blog.

Unless I'm mistaken, the original concept of the blog was merely as a jump board for people to publish their personal opinions, views, or otherwise meaningless twaddle. A forum is exactly that. A discussion forum.
