Youtube feeds prevent accurate metrics from being grabbed.

It seems that Youtube user channel feed links always have a "&feature=youtube_gdata" part appended to the url which I believe breaks the way that postrank is looking for metrics from other services such as twitter or reddit which generally link to the "clean" url.

In order to work around this, I believe that postrank should remove the "&feature=youtube_gdata" from the youtube feed urls or at the least get metrics by ignoring all "&" extras.
