I started a astore a couple of months back. It got into the G index within a week. I didn't do much backlinking coz' I was just too busy a that time, but it anyway stayed within the first 3 pages in google. Last month, I had more time on my hands and I decided to run thru my inventory. I found that my astore was not in google anymore, not even in yahoo (luckily still in m$). So, I started PRstorming, social bookmarking, and built tons of other links. After about a week or so, it finally came back in google ! Though it's basically not ranked for any of my desired keywords, but you know what, seeing it re-appearing in google index feels so good Now I'm working on a linkwheel to try to push the serp. I'll update the progress if anyone is interested.
