Page Rank Back to 6

In the past, this blog has a page rank of 6 and then dropped to 5 due to changes in Google's Page Rank algorithm in 2007 and then it goes back to 6 again in 2008 and since 2008, it dropped to 3 (i don't know why). I didn't do something about it. I just keep posting and posting and that's it.

This morning, i found out that my blog's page rank is now 6 again Please don't ask me on how to achieve this, as the only thing i do to maintain this blog is by updating it regularly (i try to push myself to write daily). One thing i note is that there are some website that aggregate my blog and created a backlink to my blog which should increase incoming link from outside site. I believe that will increase my page rank as well.

PR Goes Back to 6?

When i browsed my own blog, i noticed that my Google Page Rank extension showed 6 on the status bar, meaning that my page rank has increased and return to the original value (it was originally 6 before Google changed his algorithm and dropped my page rank to 5). Some blogger was quite lucky to get their page rank back in just a few days, but it took me more than a month to get it back to 6.

I'm not really sure if it's 6 or just a cache of the page rank, so if you have page rank extension, can you confirm it by giving comments on my blog. Curious, that's all...

Thanks

Changes to Google Page Rank

Some sites have reported that there's a possibility that Google has changed their Page Rank algorithm, resulting some decrement to their page rank point, including YouTube from 8 to 3 (From Googlified). From SitePoint, i got this new update:
# Boing Boing: Was 9, now 7.
# Engadget: Was 7, now 5.
# Forbes.com: Was 7, now 5.
# New Scientist: Was 7, now 5.

My blog is affected also. It has dropped from 6 to 5 currently. Does your blog gets affected also?
