&gt; A good idea does not have to appear to be good after 15 seconds, in fact, it is probably a warning sign if everyone thinks your idea is good straight away as then it is likely that someone else has had it and is working on it, or there is some fundamental flaw that you have missed.<p>Have you ever been in a class where you feel lucky when someone asked a question which you felt too embarrassed to ask? There is a class of products, which would feel immediately useful but no one feels like building them.<p>For eg, Errorception[1] was probably the first Javascript error tracking product made. I could guess people before this tested manually on all browsers or had a custom front-end tracking solution. As a product, it felt immediately useful, one more headache resolved but it took till 2011 for the product to get made although the problem was always there.<p>Of course, products like these won&#x27;t make billion dollar companies but definitely be useful to large number of people.<p>[1]: <a href="https:&#x2F;&#x2F;errorception.com" rel="nofollow">https:&#x2F;&#x2F;errorception.com</a>
