Think about the wall plaques or audio guides that shape your visit to a museum: They're no different for visitors more interested in history than art, or those who want to dive deeply into a particular artifact and skim past others.
A Boston startup called Spotzer wants to change that, by letting you use a smartphone as your guide, and deploying Bluetooth "beacon" technology throughout museums so that you can chart your own course.

To the list of services that can be summoned with a few taps on your smartphone, you can now add laundry and dry cleaning. A California startup, Washio, launches in Boston this week. The company pays contractors with their own cars — they refer to them as "ninjas" — to zip around town picking up and dropping off sacks of clothing, and promises 24-hour turnaround.
