SEO __ Homepage disappeared in Search results after Page Title hidden.

Hi guys,

I’m having another puzzle here, and so far googling the answer didn’t help..

I’ve hid Page title (in Twenty ten) by this CSS:
#site-info a { display: none; }

And initially I also touched Header.php on this, but i think that didn’t work, and supposedly I brought all to it’s original version, which looks now like this:

______________________
<title><?php
/*
* Print the <title> tag based on what is being viewed.
*/
global $page, $paged;

wp_title( ‘|’, true, ‘right’ );

// Add the blog name.
bloginfo( ‘name’ );

// Add the blog description for the home/front page.
$site_description = get_bloginfo( ‘description’, ‘display’ );
if ( $site_description && ( is_home() || is_front_page() ) )
echo ” | $site_description”;

// Add a page number if necessary:
if ( $paged >= 2 || $page >= 2 )
echo ‘ | ‘ . sprintf( __( ‘Page %s’, ‘twentyten’ ), max( $paged, $page ) );

?></title>

So after successfully hiding the title, the Home page disappeared from Search results (google, yahoo). Before it was there, with no description though. Just the page address.
Now only .net/bio etc pages of my web-site show up in google search.

I did add meta description and meta keywords in Header.php, but this didn’t seem to count when search engines decided to leave my Home page alone, just counting sub-pages.

Do you have an idea why this might be happening?
