After searching for all firstov.com page views indexed by Google, I've noticed that some sections of my web site display navigation menu text in the Google results instead of displaying a nice intro text that should have come from the description meta tags. This was caused by absence of description in the page header and by improper layout design of the web site. Apparently I had navigation section in the <div id="navigation"> placed before the main content <div id="content">. And the text from navigation block went straight to the Google index creating non descriptive results in their search pages.
The solution was easy: swap these two divs and now the template looks like this:
<div id="main">
<div id="header">
<!--header html-->
</div>
<div id="content">
<!--main content-->
</div>
<div id="navigation">
<!--navigation html-->
</div>
<div id="footer">
<!--footer html-->
</div>
</div>

Using proper stylesheet the content block gets displayed first which fixes my problem.
A very simple way to see how Google's robot "see" the page is to use any text based browser (such as Lynx for instance): lynx -dump http://www.firstov.com/blogs command will display the page content without any pictures.
