I wouldn't say that it "makes more sense" but it has more units between freezing and boiling than Celsius without going into decimals. Particularly within the standard range most people care about -- outside temperature.
That's not to say it's "better". It serves its purpose though which is letting others know how hot/cold something is.
Well, my emphasis was more so using the same measuring system that the rest of the world uses. I don't care about "trying to fit in", but the Metric system is at least "equally as effective", so it only makes more sense to me to use the Metric system.
Why would trying to change now be any worse than trying to change at any other time?
"Now" was in reference to when people had become accustomed to our current measuring system. It isn't "now" as in "2012", but whenever society had fully integrated the current system.
