hi mbt,
ok i see what you mean now

the comments component is using the default joomla .readon class, which is why it is getting the styling. I would recommend you remove the styling altogether. The selectors you should remove are located in your customize.css file:
#center .readon {
display:block;
float:right;
width:86px;
height: 21px;
background: url(../images/readon.jpg );
text-indent:-7998px;
margin:0 -2px -2px 0;
}
.readon {
display:block;
text-align:left;
width:125px;
text-indent:5px;
font: bold 1em sans-serif;
background-image: url(../images/readmoreicon.png);
background-repeat: no-repeat;
background-position: 7px;
}
Remove those completely and it was revert the links back to normal text.
Also, i noticed your content is not in a paragraph (ie, wrapped in content here). Adding that will sort out the spacing issues
Cheers,
Chris
