Software Project, Ideas welcome

Hello

I'm a experienced software developer, and i'm currently thinking of doing a new project in my free time.
But ive been away for a while on bhw, (had running some profitable sites until i got banned on google).

Are people still interested in bots etc these day's?
And with a bot i mean a real bot that dont use's the browser to listen in.. like many do

All ideas are welcome.

Ps: also mention the operating system (windows,linux,andriod etc...)

Regards Me

People are always interested in bots, but the competition is high these times I think, so it has to be an innovative bot if you're going to make one
