Could anyone just give me a good idea to develop? Just a simple idea you know, one I can make just some billions of it. Nothing more :) Thanks!

you mean you want "a small loan of a million dollars"?

@erasmuswill Just a little idea I could use to make myself a millionaire :)

write an app which stops rain

@gaboratorium could do that in HTML I think...

...and some cloud services

@gaboratorium including the umbrella? :P

i think the bubble poped a long time ago

@youness what do you mean?

Write an app that allows devs to rant about their problems... Oh wait....

@gaboratorium I see what you did there.

Take a look at craigslist, so many startups have cut that up into very profitable niche companies (airbnb for short term rentals, lyft for ride sharing, etc). Lots more there to build a product around, and better to be close to the exchange of money from the start
