Taskrabbit for everything: The central use case of Taskrabbit is handyman stuff, like assembling furniture or putting up shelves. But you can use it for almost any well-defined task, including online stuff. I've only used it for a couple of tasks so far, but have a number of other things I'm hoping to try. So far I've used Taskrabbit for:Finding me a flu vaccination appointment when the local pharmacy didn't have any;Picking up medical prescriptions (basically paying someone else to be bored waiting in line for me).
