I am not a native English speaker, I might not get the feel of your domain name right. Having the word bubble in your name doesn't really convey trust to me. Do native speakers feel the same?
I'm a native English speaker and that was the first thing that came to mind. If I saw this link anywhere other than an Ask HN post, I would automatically pass on clicking it.
It doesn't really have any connotations for me in this context. Obviously, if it were to do with investments, 'bubble' would be an odd choice. In the context of invoices I don't think it really means anything.
Agreed, I thought this would be a cool css / js tooltip effect or something.
I thought it would be some article about the difference between cash and accrual accounting, and how temporary differences in these numbers can cause (short-term, but potentially fatal) problems.
:) sorry to disappoint! sounds like a good idea for an article.
I'm not sure I'm disappointed, really; just slightly surprised.
