Well... I don't think it should be completely shied away from... my dad met my step-mom on... i think it was loveandseek, and he hadn't been happy in a long time. The only reason I didn't approve was that they got married six months after meeting, and it threw me into being a big sister, but that's beside the point.
I honestly prefer the natural way, getting to be friends and maybe something more if God intends. But no, i don't think it's right or wrong... it's kinda like a friend setting you up with a blind date... only it's you setting yourself up with some not-as-blind dates...
