Yeah, people have been using things like Mint for ages, too, and it's not like professional accountants hosting Quickbooks on their ancient Windows boxen is any less terrifying from a security perspective than a ledger SaaS startup...

Personally, I'm likely to stick with Gnucash until or unless it becomes completely unsupported, but Intuit needs some real competition and it would be great to have more choice available.

gledger looks like a neat project, will check it out!
