Donna-- with a short stem, you also have the option of reversing the stem if you want the same effect as having handlebars with "more sweep". The downsides are that it doesn't give you as much adjustability as tightwad's solution, and that people who know bikes will think it looks kinda funky.

My girlfriend's old bike has too much seat-to-handlebars distance so I reversed the stem... which changed the riding position to "cruiser-ish" from "regular MTB".
