I discovered what had happened to the rest of blog search when I went to look for a post of mine from last April titled I began this post because I wanted to find my post "A sense of bewronging", IceRocket and Blogpulse only find more recent posts that refer back to the original. A search for "bewronging" on IceRocket, I found, produces three results: A Week of Tweets; 24-30 April 2011, by Tom Graves; Mind The Gap: You Are As You Are Eaten, by Cliff Gerrish; and Real Names, by Digital ID Coach (Judi Clark). Clearly there's a time cut-off here. IceRocket has decided that old stuff isn't worth indexing.
