Since this is interesting and nobody has commented yet, let me say as a side note that I like how Mr. Baez emphasized the difference in orders of magnitudes here: The neutrinos from the Big Bang also carry about 10^90 bits — a bit less than the photons. The gravitons carry much less, about 10^88 bits. A difference in exponents of 2 might not look like a lot but one can almost ignore any of the earlier numbers once a larger exponent appears.
