Here's something that I found recently - results of an "ideal-type" voting android app
For those of you who are too lazy to go through the whole list (click for a bigger picture), here's how T-ara members ranked amongst those from other girls groups:
6th - JiYeon
31st - EunJung
38th - SoYeon
39th - HyoMin
54th - BoRam
92nd - Qri
129th - HwaYoung
In short, the android users like T-ara in this order:
JiYeon > EunJung > SoYeon > HyoMin > BoRam > Qri > HwaYoung;
this is definitely not how I like them, which would be closer to something like SoYeon > Qri > ...
One other interesting thing to note from this voting is that T-ara came in second, just after SNSD, for the average score.
