I'd ask what your product is but someone who created an account an hour ago and pulled out some unsubstantiated large figures probably won't give specifics.

Sure certain products can pull in stupidly large revenues, but this is an example of a person with limited time applying a small amount of time to a niche and being nicely profitable.

By that logic, doesn't your lack of success with no advertisement or SEO on the first product prove your second and third products don't exist?

I don't know what are you talking about... Sorry.

If you take your first experience: "My first crappy product made $8K a year in profit 0 advertisement" You might draw the conclusion that '0 advertising is no way to build a company'. In which case you'd have never bothered trying the others.

Adwords and SEO are extremely valuable and profitable when done well. Bear in mind that Bingo Card Creation is a relatively small niche. There are people doing finance related things with adwords who make millions.

That's not really true. You would be encouraged if you made 8K off a crappy product with no advertising. You would think that making money is easy and that you could do much better with a less crappy product. True or not, that's how I'd read that statement and feel about that situation (which is actually pretty similar to my actual situation).

OP "This is all mildly interesting and nice, but honestly $30K projected for this year is nothing."

I was suggesting that if the OP applied his own logic...

Personally I think making any amount of money is cool and something to build on.

He made $30k at 5 hours a week. That works out to $120/hr. Not bad.

Last year only, he worked on the project for four years and I don't think he made that amount in the first year.
