I suppose this space of hosted business dashboards is fairly new (2-3 years?) and services will improve. Last time I checked, Geckoboard wasn't allowing tables and arbitrary HTML. I also played with ducksboard and leftronic. Each of them have some strengths and some weaknesses. GB doesn't store your data while ducksboard does, GB is cheaper than other dashboards, leftronic has better maps than others etc.

Does anyone know of a dashboard that I can host myself?
