Just now I check my PR at checkpr.org..it shows PR2 only..damn..but the Google toolbar still show PR3..==" I want PR4 la..not PR2 la..

lol..PR8 then you got the ALMOST same value with Google.com d.. Problogger.net also PR7 only la..perhaps PR8 is for authority sites..or Google for other countries..lol

Anyway..bad news for my blog this time..dropped to PR2..but search engine ranking improve..lol... after I've stopped optimize the keyword for make money blogging and make money blog..my blog rank dropped to 2nd, 3rd page or so..then yesterday pop up to First page again..lol..

But still bit disappointed la..I thought I would get PR4 1.. but nvm..next time..

Yes..Google does..but you need to do some works..
If you don't mind..check out my previous article about how I get back my PR after penalized by Google..

Perhaps he have PR2 or PR3 before? and get penalized to PR0 after selling links?

I got PR2 before I served TLA, but after 2months my PR dropped to PR0. After I've taken down TLA, and do the following steps that shown in my post, I get back PR3.

commenting on nofollow blog helps in SERPS too?

I think you have to send them reconsideration letter and tell them what you've done.. I did it and I get back my PR3 in 3months or longer..lol

haha congrats!
