I actually really like stackexchange, however, I think a lot of improvements could be had in the site interface which would boost participation.
The real test of the usefulness of a site like this is customization.
As it stands, the rendering of the subdomain chistianity.stackexchange.com loads the UL container tag with "Questions Tags Users Badges Unanswered Ask Question" as the anchor lists.
The div id "mainbar" is therefore shown on the resulting page /unanswered along with a further div id of "subheader" and a level 1 heading of "Unanswered Questions". The div id "tabs" has the following links: "my tags newest votes no answers".
That last one really is the head-scratcher in all of this.
Correct me if I am wrong, but aren't Unanswered and "no answers" synonyms if not functionally identical?
An ideal rewrite would have a more powerful thread sorting, watch lists, hide lists and clear distinctions which eliminate redundancy.
