I say yes, I mean it's not mod-able but there is still plenty of topics to discuss, and I guess you can consider Custom UI somewhat modding.
wc3search is a great wc3 site. Darky is a great hoster, and probably has made the best wc3 modding site ever. I'd like to see him make another victory with a WoW site.
It would require much more attention for a while, but I don't really see any HUGE changes going on here as it is.
However, I think Darky should make it based on his opinion not others. If you have ever had a site/forum before and you have many friends on it and you wanted to change something you sorda become dependent upon their opinions. But considering that this will be a seperate website I wouldn't be too concerned.
