Stack Exchange

My advice:
Don't share your knowledge for free on Stackexchange, you will never be rewarded for it. Better create a blog. A blog can bring you job, customers, fans, money.

The information quality of this website is over-estimated. Normally, we should get answers from very wise users. However, they are users on this website who don't deserve their points and don't really answer the question. They just debate about the question without dropping a line of code.

From a technical point of view, many questions should be simple to solve. The person who answers should have the necessary lines of codes, lines of command or directives. However, Most of the time, some argue and you can do NOTHING with what their answer. They just fill up the blank. So, you read the 2 or 3 first answers to discover they aren't helpful for your problem. So it means that you wasted several minutes reading.

How it is possible since these answers get voted?

I am suspicious about the +1 those low-quality answers get. I wonder if some people didn't create bots just to get a better ranking.

You may read 5 answers thinking they are helpful and after thinking about it, you discover none of them are useful for your problem. Stackexchange is an ersatz of a support website.

Just like for Quora, people pretend to be knowledgeable about subjects, but they don't.

There is only a small percentage of knowledgeable people on Stackexchange, and those people are never rewarded just like they should.

Stack Exchange is an index to a collection of question - and - answer sites that cover a range of topics as varied as general physics, Ubuntu, Wordpress, cooking, photography and many other subjects attractive to geeks and nerds such as myself. Why do we think there are only three generations of fundamental particles? Who knows? Suppose that $g$ is a bijection on the real line, and $g^{-1}\circ f\circ g$ is a $C^\infty$ function whenever $f$ is $C^\infty$. It seems howlingly obvious that this can only happen if $g$ is …

Well, I'm fairly sure you don't need me to explain that.

The good thing is, that unlike just about every similar site out there, there's no registration required, not even for free. Just ask your questions. And there seem to be some really good answers and problem solvers here.

If you acquire a reputation for utility and knowledge, you'll also acquire points that give you some extra goodies, such as the ability to create new tags and take part in chat.

Definitely worth a look if you need to know how forgiving you need to be on new employees, or what you can do with frozen eggs (both genuine questions), and "throw them around" hasn't been a successful answer for either, so far.
