Recently I have been informed that the PageRank provided by pagerankstatus, a Firefox extension is different from official Google Toolbar. Since, I have been slightly involved with the development of this extension, I have studied the reason behind it.
Example
Target site: http://benmccann.com/
Pagerankstatus's PR: 4
Official Google Toolbar's PR: 0
Reason: Google's bug
Analysis
Pagerankstatus
What pagerankstatus requests: ...features=Rank:FVN...
What Google returns: Rank_1:1:4
Official Google Toolbar (IE)
What Google Toolbar requests: ...features=Rank:...
What Google returns: Rank_1:1:0
Official Google Toolbar (FF)
What Google Toolbar requests: ...features=Rank...
What Google returns: Rank_1:1:0
Google info XML file: ...info:...
PR inside XML file: 4 (This might be the right PR. Same as of pagerankstatus.)
Conclusion (Google bug)
Official Google Toolbar has downgraded the category/directory option; that's why now not sending "FVN" as "FVN" is for category. But, Google is supposed to return same PR for "Rank:FVN" and "Rank:", but returning different results. Let's hope, Google will fix this bug soon.
To my knowledge, most of the people here in India pronounce Opera as Oh-pe-raah. Some software professionals just started a new version of pronunciation: Oh-pey-raah. Because of the confusion, I decided to ask the Opera developers. To my surprise, they told me the right pronunciation of Opera is the first one in http://www.answers.com/opera That is, the right pronunciation is AH-per-ah

It's quite ironic. But, once I had shown enormous interest in Google and did post my suggestions at news:google.public.support.general
What I suggested
But, sadly they didn't fix many bugs that I have reported. Here is one such bug list on broken GG2 (news:1092037200444279@googlegroups.com)
