I just stumbled across this interesting discussion among several typographers about the euro symbol. The discussion is from 10 years ago, when the symbol was just being introduced.

There are interesting points in there covering everything from the name of the symbol itself (some people think it should be the "ecu" instead of the "euro", others vehemently disagree), its placement into unicode and other character sets, complaints about the glyph's general form, political trouble with the guidelines set forth for its use by the EU committee, and so on...
