Application development and promotion

Recently I read some articles that some programmers got good promotion by reddit.

Some stories of them are exciting and inspiring that some programmers get succeed after failed many times.

Don’t mention how a lady could survive by making product with very limited budget less than $20, even the application development required the basic server and tools cost. Though I knew the cost requirement of the server, domain and so on, I did not realize that I low-estimate the amount.

Investment is required before incoming.

I also suspect that why the users of Chinese IT market did not pay well for the programmers. I have not used reddit yet, but as the description of reddit, many platforms of China are doing the same or similar work like it.
