I mean, I like it. Allsides.com's "side" identification are decided by viewers, so I'm at the mercy of the majority's observational skills. Luckily, they show a viewer more than just the one "left", "right" and "center" outlet's coverage, so if I disagree with one topic's assessment on which outlet should be the spokesperson for which end of the spectrum, I can look for whatever outlet in that topic I think would be better suited for the role.
Allsides.com does not fix the eternal vigilance needed for news cycles in our modern age, but it does make it easier.
