Endearing names really never do it for me. A "pet name" like "alley cat" has a meaning, is given for a reason. And other than that, i find my SL name, YT, quite cool (why else had i picked it then?)
For everyone who wants to know and did not ask yet: YT is "borrowed" from the book "snowcrash". Read up at your favorite bookstore about the content, then you know what snowcrash is about. The "family name" Recreant shall indicate, btw., that it is not exactly that YT, which would not work already from the age of the character in the book.
