Why I Don’t Link To Some Worthy Posts

Like, for example, this one by the appropriately named A. E. Brain.

When I see that the blogfather has linked to someone, I assume that it needs no further linking, unless I (rarely) have some unique words of wisdom to append to it.

Is that right? Are there really readers of this website who don’t also read Instapundit? If so, then perhaps I should reconsider my position, but my preference is to point out things that people won’t read elsewhere, for parsimony of my efforts, if for no other reason.
