It's an indication of the threat the Underground Literary Alliance represents-- of our integrity-- that the lit bloggers won't link to our site. (Just as many bookstores won't touch our products, presumably because it may piss off the Eggers crowd.) We're persona non grata in the literary world. This proves that we ARE different.
Most lit bloggers, of course, are tame and status quo-oriented, a typical example being the tedious John Updike fan Daniel Green, who represents for American lit merely More-of-the-Same.
