It is a nice idea to have a video presentation of listings or slideshow of the pictures of the listing. And we can promote our listing easily with SlideTalk.net. Let the slides speak - but what if we put 'cap' on a number of slides? Half-the-fun is gone when you have to limit yourself to just a few slides to share your ideas.
Yes, you can go pro or have a premium account - but you have to pay through your nose - as many more compatible (or even better services are available for this.)
Will talk about the price soon.
