Then give me madness. The problem is that spreadsheets are one of the most natural interfaces for data that we humans have, and even with Microsoft and Google's efforts included, current spreadsheets on a website (SoW) suck.

So let's say the y-axis is importance of function and the x-axis is compelling implementation --> voila! Right there, plotted on the graph you can see that this is something that needs to be worked on.

I understand your reasoning: you've created a spreadsheet-styled labeled grid in no time and you're pumping your fist, only to find out later that it this is way less than 1% of the effort you will eventually have to dole out to make a basic, respectable spreadsheet. The landscape is littered with 1% efforts that look good until you start working with it.

My point, though, is that this area is too important to not try harder, to not see more true attempts.
