The net is a great place to ask for opinion.

I've got a thread running that does exactly that:

New business venture: please give your opinion

I'm seeking views on a product idea my brother is developing.

If you haven't already completed the survey and don't mind sparing a few minutes, I'd be real grateful.

I'd never set up a survey before. But I was amazed at how easy it is.

I used Survey Monkey

And it didn't cost me a bean.

The data is collected and analysed automatically, making it a breeze to gauge people's views.

All in all, it's a great tool to add to your armory, especially if you're building a list or selling a range of products. Or breaking new ground.
