Im so surprised that this is getting so much attention. The only time you should listen if its something along these lines, obviously squeezed into one sentence so you dont get the opportunity to cut him off "I have this great idea (microsecond pause), im so confident that it work, (microsecond pause), that ive ['released US$50k equity loan from home','borrow $35k from brother','prepared to invest my liquid savings of 42k into it']."
If it takes the turn of you do the development/impl and ill do the "sales, marketing, requirements, design, gathering investors, watering the plants" get him/her to quantify the success they had in each area and why they no capital to make a financial investment themselves (hint: most do via house equity but wouldnt dream of touching it - too risk (i.e. make your own mind up.)
Im inclined to believe that the original opinion of this article that ideas are worthwhile and execution is important (agreed!) has NEVER been an opinion of yours, rather someone has tried to talk sense into you before you embark on slave labor executing this idea from an idea man, perhaps in exchange for 50% of nothing. Too fishy.. But hey it solves that little conflict that's going on in your head now..
