Information Week reports that IBM has unveiled a preview of its new blogging software, a component of its Workplace Collaboration Services software (part of IBM’s Lotus unit). The software offers all the elements you’d expect of a blog, but it functions within the Workplace environment and blogs are accessible only by others running Workplace software. (At least, that’s what the IBM website says: “any authenticated Workplace user can read the blog.” Does this suggest the blogs are designed exclusively for internal use? Neither IBM nor IW are clear on this point. The blogging app is available for download now; IBM will release it commercially in August as part of its Workplace Designere 2.5 package.
