OK, I should have said "from my experience". That was my experience most of the time when I was subscribed to mashable RSS, most of the time posts were deep linked to more mashable posts, instead of original source. It was a quite bit frustrating.
Anyways, I just checked the last couple of post you guys had they all seem to link to the source. The fact that you come here to reply to readers opinions, clearly means you guys care. That's good enough for me.
Thanks.
