Thanks to Trey at OpenSourceCU, here is a real example I have seen of a real social banking site, but of course its not a provided by a bank. Wesabe is … here is an extract from their about us page:

Who is Wesabe? We’re not a team of financial planners or number crunchers. We’re real people dealing with real money issues. We want to get rid of our credit card debt, are starting to think about college savings for our kids, have a sneaking suspicion that everyone else’s cell phone plan has more minutes for less money, are tired of getting stung by stupid bank and credit card fees, and dream of buying a more environmentally friendly car. We feel like businesses have stockpiles of data on us as consumers and think it would sure be great to have more information on where we spend our money so that we can make better decisions. Alone, that’s a pretty daunting proposition, but together, by pooling our knowledge, we can create an immensely powerful thing. We want to take control of our money to reach our financial goals, and invite you to join us.

OK, so far so good. They are disassociating themselves from real Banks for sure, and relating to their customers.

You download your credit card and bank account information, and then it is shared in an appropriate and private way. This from the FAQ.

What do you mean by sharing? Do I have to give up my privacy to participate?

We never share your account data with anyone. What we do is look for patterns in lots of our members’ spending — patterns that would help inform the Wesabe community about good or bad values. For instance, when we see that enough of our members shop at a merchant, we will post the average transaction that they paid — not what each of them paid, and not any information about who shops there, but only the average payment. If too few people make a payment to a particular name, though, we won’t post information about those payments, because those may be private transactions (like splitting a dinner bill). If you decide to post a tip to Wesabe, or sign up for a goal, or make a comment on a tip or a goal, your “public name” will appear on that tip or goal — not your real name or your login name, but a separate name just for participating in the Wesabe community. We never reveal the real name of the person who uses a public name (unless we are compelled to do so by a valid court order).

Finally, here is a brief extract from one of the forums. I changed the names to protect the participants.

What is bad debt? John

I like the idea of this goal, but I was curious as to what other people think of as being “bed debt”

Credit card debt is bad, and most people agree that student loans are good (even if they don’t feel good when you are writing the check).

What is bad debt to you, and why?

Bad debt, to me and the industry I work in, is uncollectible debt, debts that are written off and considered a loss.

CC debt is debt you should avoid, since it spirals easily if you allow it to.

IMO, bad debt is when you borrow to pay for something that does not appreciate in value. A mortgage is generally good debt. A car loan is generally bad debt. Credit card debt, which is usually tied to consumer purchases (stuff!) is almost always bad debt.

Student loans are generally OK but can still be a major burden for many. I think peo ……

All in all, not a bad start.
