The five holy reasons

I think that I can list five main reasons to explain why good suggestions are so hard to follow (and it doesn’t matter if we are talking about the economy of a country or the settings of a GNU/Linux server).

1. we are lazy
2. we are unskilled
3. we would like to make clear to everybody that the work of many people is useless
4. we would like to stop someone from making easy money (someone that we support or whose support we need)
5. we’ve built, through the years, a monster system that we don’t understand completely and we are very reluctant to change anything in it
