Thanks. That helps, but it appears as if the hold that Curse and WoW Interface has on the market is very strong. It will be very difficult to break into this market.
That said, I would like to make a suggestion, if you haven't already done so: Use Google Webmaster Tools to monitor your website's popularity in search results and find potential issues. Also possibly Google AdWords or other advertising service to help get the word out. Nothing's guaranteed, but perhaps they will help.
Also, try to figure out what you can offer players. So far, what you're offering developers seems to be decent, but I'm sure players are asking "why use SolidICE over Curse or WoW Interface?"
