This was suggested a very, very long time ago. But I believe that now is the appropriate time to bring it forward again, as this is a new frontier of glory and joy and whatnot. Graphs. The WA rankings are all well and good, but you can't tell how you've done compared to your last one without a perfect memory. My idea is graphs that record your stance in, say, basket weaving, and then allow you, next time basket weaving, come around, to see what you've changed.
Ten Thousand Years to the Lord of Ten Thousand Years! Ten Thousand Years to the Lord of Ten Thousand Years! Ten Thousand of Ten Thousand Years to the Lord of Ten Thousand Years!
The Dragon Throne has stood for Ten Thousand Years! For Ten Thousand Years, the Dragon Throne Stands! The Dragon Throne has stood, is standing, and shall stand for Ten Thousand Years, Ten Thousand Years, Ten Thousand of Ten Thousand Years!
I'm not personally against the idea. However a lot of people fear anything that remotely reminds them of NS2. You might be better off just keeping track of it in an excel file.
Though, thats the first time I've heard of a Graph being used to kept track of WA rankings... I think I'll add that to the list.
