What Social Interaction Do I Want With My Bank

I am trying to think exactly what a bank might use twitter for. My wife knows a lot more about social media than I and told me straight, most businesses make a mess of it by thinking it is just another channel to market their products through. This just alienates their potential audience. So, they need to tweet about something interesting. My vote on something interesting is on how they are going to prevent greed and short reward horizons for their staff from causing us another serious issue ;)

Sorry, but there is nothing, and I mean nothing, which I would like to hear from my bank on Twitter.  Blogging and tweeting are something that people do, not institutions.  Institutional tweeting is just another word for advertising..of which I already receive enough.

I'm curious to know, not so much which banks are using Twitter, but which are using it well. Will best practice evolve and allow it to get traction, or will it go the way of 2nd Life, banks on Facebook, et al? Also, Twitter is a 2-way medium - if you're going to transmit, you need to be prepared to receive. I suspect compliance will be the real Twitter-killer though - when every utterance must be signed off, it doesn't make it easy to have a conversation.

I agree with Mark.  A monthly email communique is about as much as I want to see from my Banks.  Lets face it, everything is geared to promotion, account stimulation and 'sales' of something.  Occasionally there is a useful reminder or article, but too often its a loaded survey or questionnaire invitation.
