I agree, but - people do this as their part time job, I did a research on this when DP was stuffed with these threads, people selling services for $5 and $10. I was like "so, this is how they make money online" but later after my research, these people have good jobs in the day and as a part time or in their free time, this is what they do, which ain't bad. And ofcourse, in less developed countries where the economy sucks, $10 or $20 means alot to them.
Wise words! Once freshman comes into the online business - he wants fast easy money. Of course the Digg might give you lots of visitors, but it's not easy to achieve, short-terms and eats your pressures time. The time of your life. As time goes by, we all gonna value prospectives and stability rather than short bursts.
I think many still do the "Signups and digg offers" just to get some quick extra cash. So that they can invest it into trying new stuff and not wasting the little $$ they have to start off with. It was a great read though. Thanks.
