Snape is really really good

I posted months ago my theory about how much sense it makes for Snape to really be good. I just did a Google search for "Snape is good" which resulted in quite a bunch of pages dedicated to other readers who have come to this conclusion as well, which makes the whole theory rather obvious and unsurprising. I thought the site linked to above lists the evidence most conclusively.

Lookin' forward to the final book!
