Has anybody noticed that posts have been disappearing, then sometimes reappearing for a while and then disappearing from the tag feeds.For example this post
http://western-hindu.org/2010/07/29/article-welcome-to-new-saivite-hindu/ appeared in the tag feed briefly but has now gone, though the previous post is in the same feed here, http://en.wordpress.com/tag/hinduism/3/ though it did not show up initially.
