Hiya Plateman,
Google is still in the midst of shuffling, right now, you'll see sites listing up in the top 10 that were never there before, then when the dust settles, some of them will go back into the deeper depths of the directory.
This happens every month lately, Google seems to be constantly trying out different algorythems in between their usual one, so that's why you see a lot of different results throughout the month.
The way I know this is because I have benchmark sites that always list at least on the first page .. I watch them constantly and this gives me a good look at what google is doing at a particular moment. Right now, those benchmark sites are not even in the first 10 pages.. I'll re-post when I see them there again.. it shouldn't be long now
