Have you ever noticed that, there is no link to view older posts of author from author profile page http://blog.hostonnet.com/author/sibichan

Copy pasted the below line from index.php to author.php and now its showing links to older Posts

<?php if ( $wp_query->max_num_pages > 1 ) : ?>
<div id="nav-below" class="navigation">
<div class="nav-previous"><?php next_posts_link( __( '<span class="meta-nav">&larr;</span> Older posts', 'twentyten' ) ); ?></div>
<div class="nav-next"><?php previous_posts_link( __( 'Newer posts <span class="meta-nav">&rarr;</span>', 'twentyten' ) ); ?></div>
</div><!-- #nav-below -->
