I read people on this board saying that they want to add a forum to Pligg. However Digg, Pligg type
CMS' *are* forums, and so are blogs, and /. type sites. It's all depends on presentation layout and on how the messages and topics are ordered. The messages may be in chronological order, flat or as threaded discussions.
So my suggestion would be to make Pligg more flexible regarding formatting.
Regarding posting I would like the users to contribute original content instead of posting the same old tired links, so the link requirement should be optional, maybe an admin switch.
As for what makes Pligg original, the rating of content/links by using the 5 stars or the "diggs" or positive count, I would like to see this much improved. Think of it as a forum poll! What if the user is allowed to chose, or enter his own criteria for how the story will be rated? I think this is a worthwhile addition that would set it apart from the other digg imitators out there. I sure could use it.
A user page would be nice too, sort of a mashup between myspace and digg. Sure this has been done before, (i.e. newsvine) but it can be a simple static subset of xhtml/css page.
