CrossWorld buzz: Very good. Zippy theme--yes to COME GO, TO FRO, WIN LOSE, IN OUT!--and some v. zippy fill. I'M A PC was great not only in itself but as a deceiver--suspect MetaRex was not the only dummy who thought the answer had to be IPADS, IMACS, or something like that.
CrossOver buzz: Excellent. Real people are not so likely to be bothered by the "this is too hard for a Tuesday" issue that I suspect was one part of what made @Rex grumpy. Alignment with the day is a real and valid issue for a fair proportion of very very good solvers, but I don't think it is impt for non-sophisticates.
