I loved the landing page idea. This would be very effective in one case ONLY. If you are promoting a product or a an eBook this would work very fine OR increasing an Email list by offering something for FREE. You know in this life “Nothing is for FREE”. So you are giving your visitor for an example “A guide to how to install a blog template in wordpress or blogger” or “how to monetize your blog?” a FREE guide will drive this visitor to type his email and hit the subscribe button right away. But if the visitor a PayPal Button he just click the MAGIC X button on the top of his browser. Landing pages are very effective when you know how to use them.
The peer-to-peer concept is coming to virtually every corner of human existence. That includes the hospitality industry. Through AirBnB you can actually rent out your house for various lengths of time for a predetermined fee. That gives you an extra income on your house and gives the visitor the benefit of having an entire house, rather than being crammed into a single hotel room.
