This is one of the most ingenuous uses of Twitter we have seen yet. Wesabe as most will know are a company that sorts, annotates and analyses your spending patterns based on your data. It allows tagging and evaluation of merchants.
The new function is for cash transactions which can be inputted directly at time of purchase from your mobile using your own twitter interface.
If you want to tell Wesabe your transaction privately, you can use “d wesabe” to send a direct message with how much you spent and on what. If you want to track your coffee spending, for instance, you could tweet:
d wesabe $4.15 Starbucks (coffee) # tall coffee and scone
Wesabe continues to impress, and almost make thinking about your spending fun!
Any Banks on the horizon here …. ??

cool idea, but a nice iPhone or other front end to send those updates would be even better.
@Ed … that too. But the twitter approach covers all devices for now.
The Wesabe use of Twitter is nice but the better way is to use your voice, so using the Jott.com or Twitterphone voice to text approach I think is much easier.
Even better for me is the use of Jott.com with http://www.xpenser.com They bill themselves as
Fire and Forget Expense Tracking – the most efficient way to manage your expenses and reports. They provide access via Email/PDA, SMS, Twitter, IM, Voice or from your browser. You can create an output file for Wesabe.
Either one is a great way to track expenses. I was never so accurate as I was with the jott/xpenser combo.
It is good to see other vendors starting to get it and to other means. What about pimg.fm and hellotxt integrating with Wesabe?
@dmgerbino
@david … those are all excellent possibilities. I think Wesabe had to begin somewhere, and why not begin with the tool de jour. ie Twitter. I suppose SMS is another possibility.
@Colin I think Twitter will actually let you use SMS to send info into your twitter feed, by using the Twitter SMS local number, to receive your details..
Will have to try my hand at wesabe soon, it looks like a promising way of keeping track of the spending! Now what to do with all the physical receipts?
