this is my theory:

Google's main index cannot take in any more domains. So Google's solution is to create a new, separate index (similar to the supplemental index) for new domains/sites. Sure behaves like the supplemental. yields serps to site: queries as well as queries with small result set from the main index.

the only way google migrates domains/sites to the main index if google removes complete, old sites (my site is missing!) from the main index. the question then is what algorith google uses to remove old sites from the main index and selects new sites from the "sandbox" index.

from what i see, the algorithm appears to be nothing but pure random chance.

by the way, have you noticed that the total number of pages in the main index has not changed in more than a year?

controversial theory but sure explains all the symptoms we see.
