In fairness, remember that there are cultural difference among JavaRanchers. Those in the US might balk at someone asking for business ideas, although at the same time, people have made millions of dollars from business plans involving "work from home," "stuff envelopes," and helping transfer large sums of cash from Nigeria (I never said it was the people who answered these calls for work who made money :-p ).
In other countries, entrapenuership is not so common. People may have ideas, but don't pursue them for a number of reasons, and so are happy to give away ideas.
Heck, here's one. Look at
Friendster and start a local version.
But serious, I also recommend porn. It drives many new industries and technologies. If the issue is personal, well, someone else will capitalize on your qualms. If the issue is cultural, don't fret it, the most pious often turn out to be the most sexually deviant.
