hopefully eventually these will make it into the main CSS but here's a couple of fixes you can add to your profile's style which fix the default CSS a bit for older browsers and "shouldn't" break it for modern browsers:
/* ie5/6 fixes */
nav .links li, footer .links li {
display: inline;
}
.profile .friends .person {
float: left;
min-height: 150px;
position: relative;
}
.profile .friends .person img {
position: absolute;
bottom: 15px;
}
#comments {
clear: both;
}
the reason for this is that "display: inline-block;" is a CSS feature that wasn't fully implemented until IE7 so older browsers on Win98 (including the latest Retrozilla) will instead display items one below the other instead of side by side
