Ask HN: What are the good old ideas that still make money on the web?
https://news.ycombinator.com/item?id=3581791HN, i'm wondering, are there still any ideas from the ages of web 1.0 that are still working? For example, software license key stores etc. I feel like there are many of ones i couldn't think of as being still profitable. HN, i want some heavy TIL experience, please help me! :)
