I noted the new USDA blog. It's always nice to see my former co-workers moving ahead into the sunlit upland meadows of Web 2.0. But a warning--there seems to be a glitch. If you comment on a post, as I did, and check the box to be informed of subsequent comments, as I did, you will receive the unmoderated comments, as I do, which include a bunch of spam mentioning viagra, etc.
There's no email address for the blog to notify them of this problem. One place where transparency is not a priority in the Obama administration. :-(
