Forum GUIs suck. This could fix that problem at least partially:
Something along the lines of Flock or LiveWriter or the Mozilla Amazon Browser – this last one (MAB) does exactly that with Amazon.com product listings – which are pretty much as dynamic as dynamic can get – it’s a desktop program since it is a mozilla extension with an XUL-based GUI of its own.
Someone good at making Firefox extensions can see the source of MAB and build this extension for PHPBB, PunBB, SMF, IPB. Those IMO, are the popular (90%) forum applications.
Still further is a generic scriptable XML-based (easiest to “script”) forum reader on the lines of WinHTTrack script. I’m thoroughly convinced of the usefulness of the idea.
