The party is not over. It’s never over. There are always always always more ideas, great businesses waiting to be built, and wonderful opportunities for clever people.
Of course the “obvious” apps/website have been built — do you know why? Because they only seem obvious in retrospect - most weren’t obvious at the time they were built. And even if they were, implementing was harder than you’d think and adoption was even harder.
Argh this frustrates me so much.
HNers: Don’t give up - don’t throw in the towel, and definitely don’t assume there are no more ideas to build with a good brain and a keyboard at your disposal.
