maybe this has been discussed before but I've been out of the loop for a while, so please accept my apologies if this is a beaten-to-death subject:
When you do a search directly from the address bar of Google Chrome, you will be taken to Google SERP that uses the /search?q=<query> URL structure.
However, when you first go to Google and then search, you will be taken to a SERP that uses the #q=<query> URL structure (AJAX driven).
All nice and dandy, BUT the results for these pages are vastly different! Anybody has any ideas as to why Google uses different data sets for AJAX and non-AJAX results and which one is more recent? Is this a mere issue fo data centre propagation?
Also, I find that in some sessions Google just serves me the non-ajax version even though I go to Google first. usually this happens when I'm logged in.
