Starship Comparison

Welcome to what may well be the geekiest topic of the week. Random Nuclear Strikes pointed out an awesome website that has size comparisons of starships from different science fiction series.

Is it sad that I recognize a majority of the ships on those pictures and have at least heard of, if not watched, some episodes of a majority of the series listed? Is it also sad that I know all the original models from Babylon 5 were lost and therefore the exact sizes of the various ships is left to estimates only?
