How do you gain any popularity at all? Most of my stuff is little hacks, but they have zero visibility. I'm sure something I wrote is useful to someone, but how do I know?
Actually I'm not planning to be popular. I'm doing it for myself and to develop interesting projects. Of course, it would be cool if it becomes popular.
In terms of popularity, if I see something is interesting, I make sure to add it to Twitter, facebook, send to friends, add to reddit, add to awesome lists and encourage participation (clear license, clear contribute.md) etc.
