First off let me welcome you to the forum, I am sure you will find very informative answers here to many IM questions
Now to help with your question:
I was no aware there had been a recent update by google. I would suggest that you simply keep adding in fresh unique content, and building up backlinks in a natural manner. Furthermore, when you do make a new post, try to go over to social monkee and post that url. This might help with your rankings to climb back up.
However, don't do any steps on massive amounts at one time or else it could cause your ranking to drop even more.
Hope my answer helps to get your website ranking again
