Yes there is. It's everyone on Hacker News! Just post about about some Unicorn here and at least half a dozen people are pretty confident they know more about the company in question than the founders or the people running it. In the future Congress can just post questions here.
I will never stop being amused by the original post about Dropbox here on HN, where a large contingent of the audience was so critical of it, it was destined to fail. https://news.ycombinator.com/item?id=8863
Many people I encounter say they can do things in days but when hired they really can't (not even close) (and these are seniors with proven experience doing things but just not very fast at all; I cannot figure if it's the frameworks as I know I could do it in days with jquery/lamp + normal hosting which is what I was asking for). Sometimes (well, generally actually always) I need something fast, not robust, maintainable and definitely not with docker/k8s/microservices etc etc. I have not found many people who can just practically do things they say they can; then in 2007 with the dropbox thing or now on freelancer sites or forums; when you hire people, even (because I understand you want more hours / security / whatever) when I can promise you that IF you can, I have work for you basically forever (considering I have a 20 year trackrecord of doing these kind of applications and i'm not stopping any time soon). I even don't care about the tech; if you want to use the latest/greatest/cv-driven crap for it; be my guest, as long as it works and delivery is fast. Seems perfect for people; I cannot find any that go beyond big talk on sites like HN.
