Google has been experiementing with a blogging system for corporations. Its called Blogger in Google (BiG) amn we may see it soon. Here is an screenshot.
"Google Inc., which implemented an internal Web log system behind its firewall about 18 months ago, has seen tremendous benefits from it and may in the future consider providing tools and expertise for this purpose to interested clients, a Google executive said.
Google deployed an internal blog for its employees shortly after acquiring the blogging service Blogger in early 2003, and since then Google staffers have found many useful and creative ways for the internal blog, said Jason Goldman, Blogger product manager at Google.
"Since then, we have seen a lot of different uses of blogs within the firewall: people keeping track of meeting notes, people sharing diagnostics information, people sharing snippets of code, as well as more personal uses, like letting co-workers know what they're thinking about and what they're up to," Goldman said. "It really helps grow the intranet and the internal base of documents."
Google executives have talked in the past about the company's internal Blogger implementation, called Blogger in Google (BIG), and a Google employee even posted a screenshot of a BIG page last year".
