If the Social Network combine with an auction site, what will happen? Let me guess, the last time you pay money for some stuff at internet is in what kind of case?
1. You have seen a beautiful model wearing a beautiful dress, and you want to be beautiful just like her...So you paid money in an auction site.
2. You have seen an open box article and be enticed to buy the same stuff, so you take out your VISA credit card and...
3. Maybe you surfing a shopping website and forgot your lunch, then you careless paid these items.
Okay, above three reason you paid money are Similarities. One at the auction site, the others are because the influence of "blogs" and "social network".
Try to imagine that if the auction site and social network "combined", what will happen?
I dare to say that the site will become a monster because the website will monetize the flow and E-Wallet (included be a middleman) to a huge amount of money. Maybe the auction site and social network can through "cross-industry" to combine and share the profit.
Status analysis
I guess the first one complete cross-industry alliance company is "Taobao" and "Sina Weibo". China monetize the website flow and auction site are done very well, and do anything are faster than other country. But all in all it just prediction, let us observe the future.
The second one is "Google". Why? because google already have a almost perfect E-Wallet system and have a shopping site "Google play" (they not only sold the software, but Nexus 7 and then quickly sold out) and "Google Shopping". Of course, there are a good social network "Google+" too! Over 100 million active users per day.
I think the "Broken Information" is a good thing and a bad thing too. Broken information let us always get the latest information, but nearly 80% are spam. Nowadays, more and more broken information appear in our Facebook or Twitter, and a good filter is necessary.
Google+ have a good conception named "Circle", we must classify our friend and give these circle a name. Maybe you can create a circle named "Spam" or "Unwanted" to classify these friend he always post junk information. In my opinion, Google+ is a better platform to merge the EC (Electronic Commerce) system than Facebook or twitter.
The social network is an unexploited gold mountain. Although so many people open it everyday, but no one finished a great monetization.
Where we go tomorrow? heh...
