Does anyone have any experiences with Domain Flipping (aka Domaining)?

I recently read about Domaining and I thought it would interesting to try it out and make some profits out of it. However, I noticed that not many people do it and the process seems to be too good to be true. Just buy a good naming domain for a low price and hope that someone needs it for their own website and sell it higher than what you bought it for.

Any help would be appreciated! Thanks!
