the get_excerpt function on WordPress shows the first 55 words of your post, striped out of any special formatting eg: links, bold, etc. I wanted to change it for a blog I was developing so I traced it back to the function wp_trim_excerpt in the file \wp-includes\formatting.php. In this file you can change the value from 55 to , in my case 100. Just change the line 786 which should look like this $excerpt_length = 55;
Please remember that this will change the default value for all you excerpts.

Hi Alex,
Conceptually, this is a great idea. In practice, you are suggesting that someone modify WordPress’ core code which isa really bad idea. Instead, they should use a filter “hook.” They can add this to their theme’s functions.php file to do the same:
add_filter(‘excerpt_length’,'set_my_excerpt_length’);
function set_my_excerpt_length($length) {
return 100;
}
This works for WordPress v2.7 and later, see:

HTH.
