I've got to say, I'm not a fan of the online ads or widgets with sound. Yes, they look and sometimes even sound cool, but I still have a terrible startle whenever a wave or thunderstorm suddenly crashes through my computer. I'm a multitasker, so I then have to figure out which recently opened page has the offending ad, which is often a challenge as many people--this blog included--have a parade of widgets along the margins. It doesn't help that I often listen to music or a podcast while I'm working, so the volume is turned up and really makes the sound effects prominent.
How about you--YES or NO to widgets with sound?
