&gt; 2. Porn search engine<p>Sounds like a good idea. I wonder why isn&#x27;t this a thing yet?<p>Edit: I googled &quot;porn search&quot; instead of using DDG and found out that is a thing. Looks like, there are tons of porn search engines. That means it&#x27;s not enough just to create one anymore. Some unique advantage is needed, isn&#x27;t it?<p>P.S.: My humble observation is on Reddit you get downvoted for &quot;Good try Zuckerberg&quot;, &quot;they&#x27;ll steal my idea&quot;, and not accepting &quot;idea is nothing, implementation is everything&quot;. Looks like that&#x27;s not the case here on HN.
