I agree with Jeff here. I found Gennii's reviews of other magazines pretty much a waste of space. If there was a magazine there I was interested in, I was already getting it. Unless for some reason I couldn't, in which case the reviews did me no good. To make matters worse, by the time an edition was reviewed it was already a back issue.
Still, I think that magazine reviews are a good idea -- just not on an issue-by-issue basis. Perhaps a better plan would be an annual review of magazines -- or maybe one magazine reviewed each month or two. Rather than looking at specific articles, such a review would examine at the type of material covered, general quality of the publication, etc. That could help folks decide which as-yet-unsampled titles they'd like to try out, and would provide information more useful than "what you've already read or already missed."
