Ledger and the accompanying Emacs major mode are both written and maintained by Emacs maintainer John Wiegley. I use both to manage my finances. I'd love to hear about Hledger though; can someone tell me why I might switch to using this?
If you don't know hledger I highly recommend this video

This my first time seeing Hledger let alone the Emacs integration so thanks for posting this. I've previously used and.co for tracking work, costs and invoicing for some simple contract work but the idea of having a plain text alternative that I can work in Emacs with is worth investigating.
