Just my 2 cents: Despite comments like "wrong tool for..." this gives great elasticity when it comes to data manipulation, you can grep it, put in RDBMS, make csv/graph/one large flat file out of it, keep it in VCS etc. Sure you can use one of billion apps to do that, but then what's the point of developing your own solution to anything, just buy/use someone else app. Keeping your financial data in cloud for me seems like so-so idea. Of course there's emacs mode for it ;) (http://orgmode.org/w/?p=org-mode.git;a=blob_plain;f=contrib/...)
