[Opinions] as in Loudon Wainwright?
as in Rufus and Martha Wainwright's father?
In that case, I totally and completely love it. I love the whole Wainwright family and would totally name kids after all of them :-)
The name on its own, on the other hand, I think sounds just to trendy for comfort. It's not that it's a bad name, I fact I rather like it, but there is always the posiblity that people will see you as just another one of "Those Namers".
