The ability to outsource data collection and have it populate a formatted spreadsheet in near real-time is fairly impressive (speed will probably differ on attractiveness of the task).  Often, the steps required to set up a MTurk task can take as long as the data collection itself, and afterwards you are left exporting to an unformatted Excel sheet.  Making sure to name data-labels correctly, populating data fields to randomize among workers, and other tasks can further complicate things; judging from the demo video, Smartsheet seems to handle these parts of the process fairly easily.

Unfortunately, good service doesn’t come free, and using the Smartsourcing feature requires signing up for a paid-account as well as the Smartsourcing fee on top of that, so I didn’t get the chance to try it out, but I would be extremely curious to hear about anyone’s experience with the service if they do try it.
