Page Rank

I will never understand this whole page rank thing. I am not complaining at all.  I am happy with my blogs, and how they have survived in the past.  My question is this:

How do blogs that have not been updated in MONTHS get a PR3 or PR4? 

How, Google.

How?

Are You Kidding Me?

Last week, the page rank on this blog went from a 3 to a n/a. At that point, I decided it was the perfect time to switch to a dot com, because doing so would drop my page rank anyway.

So what do you think happened this morning?

I went to ppp, checking opps, and one of the ones I qualified for said "PR3".

WHAT?

Sure enough, google gave this blog back it's page rank, but under the blogspot url. The dot com is still n/a, ppp just hasn't switched it over yet.

Is there a way that I can contact google and have them switch the PR to this url, since the blog content itself has not changed? Would they do that?

Don't Know

Last night, I noticed something weird. The little page rank checker on my toolbar said this blog is no longer ranked...a big N/A. Yesterday afternoon it was a 3. I checked using the checker tool, and it still says 3 on one, 2 on another, and N/A on another one. I don't know what to think. I checked on ppp, because they show rank, and it's still a 3. The last time I was dropped in rank, it showed up immediately. I don't know what's going on. Anyone else having issues?
