Does Google want to see more text on pages than before?

I just put up a page and let some of my signature links point to the page just to get the page indexed in Google.  The page was indexed in Google for a short while, but I noticed that the page is gone from Google index now.  It has no outbound link, so it has nothing to do with its neighborhood.  So ... I am suspecting that the page has so little text that Google just dropped it for now, which is fine; I can just add more text or set up a real site properly.  However, I wonder if Google wants to see more text on pages than before.  I seem to remember that it was much easier to get a bunch of pages indexed in Google in the past.  Is this just my imagination?

I once had a friend's page (3 mths ago) that was indexed, and it is still in google's cache and being indexed.
That page has nothing but a logo. Now that the page is updated, google still shows the old page.
Sometimes I just don't understand google.

Making a long story short, Google is broken.  Longer explanation is that Google crawls sites with high PR and high TrustRank, so Google tends to have the latest pages in those sites cached, but Google barely crawls sites with low PR and low TrustRank, and thus, this creates various problems as far as users are concerned.

You shouldn't try to get a high PR and then try to create content.  It should be the other way around.  You should focus on creating content, and then, you should get a high PR as a result.  That's probably what Google is implying.
