Rather, you don't provide reasons to motivate people to switch to your font and stick with it.
You have mainly two kinds of users:
- those who have always stuck with whatever font came up by default in their text editor or terminal emulator.
- those who have gone through a phase of experimenting and tried a good bunch of fonts, then settled.
When you motivate the former group to experiment, they will tend to go into the second group: once they get into the workflow of installing fonts, they won't just stop at the one that was suggested to them first.
The second group is harder to motivate to try new fonts; they will do it if there is some compelling reason they can understand /before/ installing.
You don't explain how your font stands out above the competition. Or, maybe the personal angle: I tried these fifteen different fonts and still had to make one because X, Y, Z, so here it is.
