From Editor & Publisher: an update on blogging and journalism from the Interactive Media Conference in New Orleans.
It's an interesting little discussion on journalism and blogging. I particularly like what Tom Regan of The Christian Science Monitor does with his blogs: one is personal and the other is for information. For bloggers who are concerned about their identity and about getting flamed for posting personal stuff, this is possibly the best option.
A blog is just a blog, a limited form of media. Thinking one can put oneself totally on one particular blog is like thinking you can judge a book by its cover.
Besides, if you think about it, you might want some people to know one aspect of you, while others know another....and their might be really good reasons besides Fear of Flaming to keep the personal separate from the professional.
Just my $.02 on that matter.
