Here's something very interesting from Google - Helpouts. This is where people can get and offer help on-line to get a helping hand with whatever it is that they need help with. So far you can get a Helpout for setting up printers, cooking, health and fitness, DIY, and many more areas. The idea is a simple one, say you need help with learning to play guitar - there's free helpout where you can access an expert live on-line who will help you out. The number of categories is quite small, and the variety of Helpouts is still low - but this is certain to grow. Some Helpouts link to YouTube channels - here's a Google video with more information:
To me this sounds like a great idea, even though it is still in its infancy. The costs are from free, to $1 a minute, to $25 per Helpout. It's an interesting model that I'm sure Google has run the numbers on - their revenue sharing model (38% for Google, 62% for content provider with AdSense) is sure to attract people who can offer their expertise on-line. Think of that time you rang your Dad to help you out when unblocking a sink or fixing a plug. As long as you have a computer - help is never far away.
