I have to say four, because although I work in IT (telecommunications area), I'm way better at some stuff than others, partly due to lack of interest (ok, the great majority). My husband just loves fiddling with OS's, for example, and I just know how to get around it, make some changes to the regedit, etc. (your talk in the developers area goes right over me most of the time). But I love databases and programming, and am coming to grips with communications (I've been recently "adopted", lol), and am considered an absolute whiz at "ofimática" (Spanish for MS Office et al)... Queen of the spreadsheet!!
