How to find a micro niche without Micro Niche Finder Software

This is me, speaking again !
I`ve been again in some trance-like unproductive mind-set these days.
It can happen often, to someone who has so many things on his\her`s mind + more if you are in this primitive earthly activity, such as make money online scheme.

But.. Anyways i came back to.... how to call it .."reality" ?
So to get back to the message:

A couple of hours ago i`ve done some research for the best idea how to make $5 a day. And of course. Nothing really usefull on the net. Eccept one idea!

I`ve found couple of forums and blogs in which there are people.... who
are actually advicing their readers to start making houndreads of MICRO NICHE websites and blogs in order to have "multiple income streams".

Becase the basic (stupid) idea is that one blog or website is ment to earn $1 to $5 per day. So one need to make at least 100 websites to earn $100 to $500 per day ?
Thats hilarious...

Who would go and make one houndread micro niche blogs ?
Who would write content for them all the time?
Who will remember so many passwords?
who would come to any idea for even 2 micro niche blogs, let alone 100 of them !

So from where i stand.. that is a bit silly idea.

Like nobody is doing it already...

Maybe they are even earning some money with it.

But definitelly not $100 per day... it is simply too hard job, to make so much websites and hope somebody will buy some product form them.

And there is one more thing... HOW TO MANAGE SUCH HUGE INDIVIDUAL WEBSITE PROMOTION CAMPAIGNS ?
