Though these concepts are new to me (I'm still working on finishing my physics BS), there are a couple of spots in this article sporting some "loose" language. For instance, the sentance "Nevertheless, the Landau pole is an awkward theoretical feature of QED, a sufficiently awkward one to make us look for a better theory." near the end of the article is ambiguous. Who is "we"? How are "we" looking for a new theory? What makes the Landau pole so awkward? QED is generally well accepted and these kinds of suggestions should be made much more clearly, and with reference to other articles/materials on the subject, I believe.

Also, I feel that allusions to superstring theory should be made very carefully in all physics articles that are not directly related to superstring theory, as it is still not considered to be a true theory by a majority of the scientific community.

Can anyone find the actual value of the renormalised charge e_R expressed in the unitless way it appears to be in QED? I'm guessing units where h=c=1; is that enough to make charge dimensionless? Anyway it would be interested to see the actual Λ scale numerically.
