The early adopters in my network have all heard about Foursquare, and Gowalla and My Town. Launched in March 2009, it was called the "breakout mobile app at SXSW by Mashable (http://mashable.com/2009/03/16/foursquare/), the adoption rate has been astounding, first by users and now by brands such as Bravo and Zagat.

And I'm sure that trend will continue, notwithstanding the fear of advertising that your home is empty and can easily be robbed (http://pleaserobme.com/). More and more people will soon be getting sucked into what Peter Shankman states in his post, "2010--The Year of FourSquare?", the "black tar" that is Foursquare.

However, I have noticed e-tailers are lagging behind, and I have a great solution for them. Just recently I added a few books to my wish list at Amazon, and I thought it would be great to share that on Twitter and Facebook. To do so, I had to open a new tab, copy and paste the link to the book and type the text that I just added such and such to my wish list.

It's really a no brainer that there should be a share button on that Amazon page, and similar pages from all e-tailers. Why not share that you added a movie to your netflix queue. Or that you just purchased new boots from Zappos. Of course in the vein of http://www.pleaserobme.com, I would not recommend tweeting you just purchased a 50' LCD television or brand new Rolls Royce.

Continuing with that model, power users---not just appointed bloggers-- would get badges and discounts, and tell their friends/followers about great deals 

Leveraging brand advocates to reinforce their loyalty and spread the news is what social media is all about. Seems like a no brainer to me, and it's not necessary to forge an alliance with Foursquare, as they already have large customer bases.   Just saying...
