I like the W3C for its discussion to be so open. For example I like to be able not to just follow the tag discussion but also to be able to participate if I think that I have something relevant to say. Why is the ldp discussion mostly going on on a list where non-member cannot post? The public list is very low activity and non of the posts this year got an answer. Below my latest unsuccessful post on the other list.
