Yup. Indeed it was that. I think since Neowin doesnt support it (within its right of course, I completely understand) there is some code that breaks it on purpose:
<div id="rep_post_596213465" class="ipsLikeBar left clearfix" style="margin: 8px 0 -8px;"> <ul class="ipsList_inline"> <li> <a class="ipsLikeButton ipsLikeButton_enabled rep_up" title="Like this item" href="http://www.neowin.net/forum/index.php?app=core&module=global§ion=reputation&do=add_rating&app_rate=forums&type=pid&type_id=596213465&rating=1&secure_key=a22a039ef12eb873c60136f56f3391b0&post_return=596213465">Like This</a> </li>Thats the code for the like button. Firebugging it, it says it is disabled (greyed out) and I cant enable it.
Thank you for giving me the idea of looking at the code.
