Here’s a service I want someone to build. I declare this idea (hell, this whole post on my blog) to be public domain. See below.
Make a web site where people can report what they did and what the bank charged them. Crowdsource this data collection and build tables where people can sort by locality, activity, and fees charged.
I’d make the web site accept anonymous reports from people. Each report would be a dynamically built sentence that the user would fill in gradually. Like:
I used __ to __ and they charged me __.
I’d use some kind of auto-complete to help normalise the data. So you might have sent pounds from Bank X in the UK to Bank Y in France.
