Free software scares normal people

Good article, but the reasoning is wrong. It isn't easy to make a simple interface in the same way that Pascal apologized for writing a long letter because he didn't have time to write a shorter one.

Implementing the UI for one exact use case is not much trouble, but figuring out what that use case is difficult. And defending that use case from the line of people who want "that + this little extra thing", or the "I just need ..." is difficult. It takes a single strong-willed defender, or some sort of onerous management structure, to prevent the interface from quickly devolving back into the million options or schizming into other projects.

Simply put, it is a desirable state, but an unstable one.

Good points, but to add to the sources of instability ... a first time user of a piece of software may be very appreciative of its simplicity and "intuitiveness". However, if it is a tool that they spend a lot of time with and is connected to a potentially complex workflow, it won't be long before even they are asking for "this little extra thing".

It is hard to overestimate the difference between creating tools for people who use the tools for hours every day and creating tools for people who use tools once a week or less.

Right. For most people, gimp is not only overkill but also overwhelming. It's hard to intuit how to perform even fairly simple tasks. But for someone who needs it it's worth learning.

The casual user just wants a tool to crop screenshots and maybe draw simple shapes/lines/arrows. But once they do that they start to think of more advanced things and the simple tool starts to be seen as limiting.
