I just wanted to report that I have gained traffic at a good percentage rate from every Google update since May. I wanted to report this because I kept complaining about Panda and thought it was all a big scam but now every Panda update is bringing me more traffic. I guess all the hard work does pay off but it took since November of last year to the end of May to see any real improvement. Its seems every week now I get more and more traffic even without any reported updates from Google. I must be on their good side right now.
It does take time but it can happen and the most important thing I did was to change the tide was to engage with viewers on what they wanted most and creating topics in my area of my niche that no one else covered yet. One thing you have to look for is that, and even though you might think its not there, they are if you dig enough.
Bottom line and my mistake was covering topics that were already flooded on the internet. Find what is not covered and you'll see what I see.
Best to all....
