The best ideas are usually not particularly clever and, at first, don't make a lot of sense or even sound silly.

"One of the biggest things holding people back from doing great work is the fear of making something lame. And this fear is not an irrational one. Many great projects go through a stage early on where they don't seem very impressive, even to their creators. You have to push through this stage to reach the great work that lies beyond. But many people don't. Most people don't even reach the stage of making something they're embarrassed by, let alone continue past it. They're too frightened even to start." - Paul Graham

These kind of ideas are, in some sense, the opposite of "sitcom startup ideas". While "sitcom startup ideas" sound clever but are actually bad, great ideas often sound terrible at first but are actually great.

"Ideas need to be contrarian, otherwise big companies will just do them, or other competitors will emerge.

So we need to find good ideas that look like bad ideas but aren't actually bad ideas, even though most seemingly bad ideas are, in fact, bad ideas." - Eric Torenberg

Most people probably would've told the Google founders that "yet another internet search engine" is a really stupid idea.

Or just look at the comments when Brian Armstrong announced his idea for Coinbase on Hacker News.

And there's of course also the famous comment when Dropbox was launched on Hacker News.

Since great ideas are often fragile, it's essential to protect them as long as they're young. The feedback by most people won't be useful and discourage you from pursuing "silly" ideas that have a lot of potential.
