Google Search screwed up my blog index

Back in 2009 I used to write a lot of blog articles until Google came and screwed up by blog index made my blog search traffic to drop by 75% and i probably lost my motivation (why write when no one is reading it ? ). Now it seems they might have fixed something and my blog search traffic has been back to normal levels, my be i will get my motivation back :).



If you look at the above stats , since Oct 2009 I used to get like an average of 150 visitors/day and then it suddenly dropped just like 30 visitors/day. Nothing really happened, same number of blog posts, nothing deleted , no changes in terms of blog settings or nothing. There was no clue why it dropped suddenly which then i followed up with google several time using their webmaster tools for reconsideration of my website to re-index or fix. But never really got anything useful from them except their automated generated message and really got frustrated and gave up,

But now some were in Nov 2010 my blog all of a sudden started to see same amount of search traffic that i used to get in Oct. 2009 with no changes ( Gave up posting sine Jan 2010). Hence not sure what really happened except i could think that Google really screwed up and they might have recently fixed it after almost an year. I wish Google doesn't do screw up anymore to anyone as they can really hamper the information sharing and exchange because it really affects one's motivation.
