Google (and the other major search engines) visits this site at least once a day and index the content.
However, on the 12th of March this year I moved my blog from the old domain (tomandpilar.net) to this site and this domain.
I put a 301 re-direct on the old site and immediately the new search engines started to visit the new site. It was being returned in search results within four days of the move. I was impressed with the speed with which this occurred.
However, today – a full one and a half months after the move, for the first time, I have received a Page Rank for this domain. At the same time, Google Searches for Links to this domain came up empty until today despite my being linked to by many prominent sites.
So I can only surmise that Google indexes sites on content far more often than it does for PR.
