From this point of view, a useful question is: what applications do you find interesting in other mobile platforms and you would like to see someone bringing to Maemo? This is also a way to pass through the 'thousands of apps' noise barrier and see what is really cool but missing for Maemo users. Looking athe list of such apps/features it is also easier to see whether such apps could fit in the known open source development model or if micropayments are required, or if it's about corporate marketing, online services etc etc. Do you want to start that list? I can say I was impressed by the imagination and simple execution of the Ocarina when someone came one day blowing in an iPod Touch.
