I dunno, I'd think just as many people would be staying in Worcester during the day because of their telecommuting as there would be keeping out of Worcester because of it, if not more. Worcester isn't exactly geared toward office jobs (even downtown), and there are plenty of workplaces in a half-hour radius of Worcester that do lend themselves to telecommuting. Downtown in particular may be struggling for other reasons (being less accessible than more spread out businesses, etc) but Worcester businesses as a whole should be seeing a net neutral effect from telecommuting.
