Leia mais Automatico

Entre no painel do Blogger, clique em design e, depois, em editar HTML.

Marque a caixa expandir modelos de widgets e procure por: <data:post.body/>

Substitua por:

<b:if cond='data:blog.pageType != "item"'>
<b:if cond='data:blog.pageType != &quot;static_page&quot;'>
<div expr:id='"summary" + data:post.id' style='display:none;'><data:post.body/></div>
<script type='text/javascript'>createSummaryAndThumb("summary<data:post.id/>");</script>
<div style="clear:both" align='right' class='rmlink'><a expr:href='data:post.url'>Leia mais »»</a></div>
</b:if></b:if>
<b:if cond='data:blog.pageType == &quot;item&quot;'>
<data:post.body/></b:if>
<b:if cond='data:blog.pageType == &quot;static_page&quot;'><data:post.body/>
</b:if>

Agora procure por ]]></b:skin> cole este código antes dela:

.rmlink {
font-size: 100%;
float: right;
margin-right: 30px;
margin-top: 10px;
font-weight: bold;}
.rmlink a {
font-style: normal;
font-weight: bold;
font-variant: small-caps;
font-family: Arial,Sans-Serif;
color: #24618e; /*Cor do Link*/}
.rmlink a:visited { color: #649dc7;}/*Cor do link depois de clicado*/
.rmlink a:hover { color: red;} /*Cor do link ao passar o mouse em cima*/

Procure então por </head> e cole este código embaixo dela:
