At least the only blog posts that seem to be there anymore are those that are hosted on blogs.sun.com.
Certainly my posts, which used to show up there until quite recently, no longer do so.
Its possible that this is just a technical snafu, but the recent burst of posts there from Oracle employees suggest a shuffling of things internally in how Oracle handles blogs, and I suspect that eradication of community posts is just one more step along the way.
Of course, if I'm wrong, this post will show up there, and I'll have egg all over my face. :-)
