Startups and projects on Habré.

Looking at the huge number of ideas that are swarming on this site, I would like to understand the reason for their appearance.

Suppose I came up with something brilliant, there is no such thing in nete and it will not be soon. Suppose ... :) I do not have the knowledge to implement it myself. At a minimum: php + mysql + css + html. What, in this case, I have options, I think?

1. Study the listed technologies and create what I have invented there.
2. Search for friends or buddies who are ready to paint for the idea of ​​what I came up with.
3. Write the project TK and look for investors.
4. Write on a resource like www.habrahabr.ru , in the hope that they will notice you and offer something there.

Now the points and to the point.
1. It is practically unrealistic for a person who has formed professionally (in another field).
2. It is also unrealistic, because as a rule everyone is busy.
3. Thought, I will reveal it below.
4. Indeed, I describe the project in detail, someone from Google, of course, reads Habr, notices my creation, writes to me and here I am in the team. But it seems to me that this is utopia ...

Of course, if the project is sensible, it will be noticed. Uncle with a bunch of money enough at all times. And of course they will launch and unleash, but ... without you.
And of course it can be so with option 3. It’s called simple: “throw”.

So back to the beginning of the article, why post on Habré? What are we looking for?

How can the author of an idea for an online resource secure his project and, at the same time, look for those who would help him with the implementation? How to avoid a bad investor?

Are there any other ways to build your projects?
