mmh..I am an user and I don't see that big of a problem. Like joerg said, we always had some criptic naming in AmigaOS even though those are abbreviations (DEVS instead of Devices) so learning them might be easier for the most part of people.
Still, I don't see the problem in memorizing that SObj: is an abreviation af SharedObjects and the .so ending means AFAIK guess what: SharedObject..
There is no way around but _learning_ how an OS is structured.
What are we users meant to fiddle around with OS files anyway? Most software comes with installers, the one that don't might have a ReadMe with the install guide, so as long as this guide tells me to "copy xyz.so to sys:SObj and mynew.library to Libs: or better with the exact commandline to copy into shell for my moments of total lazyness" I'm ok with it. I had to install manually some "a53sound.component" in ~/Library/Components on my mac. I did it once; it was no problem to find the dir even if I'm new to MacOsX.
AmigaOS has a long way to go untill it reaces the IMHO -from a beginner point of view- puzzling naming of e.g. Linux. They would have to rename all the current naming and I see reason for that to happen.
SObj: is a good name..Sobjs...sobjs..yes it spells nice.
:-p
