I could not disagree more. By putting all those utilities in a folder you essentially create a clusterfuck equivalent just doing a directory listing in the system folder. None of this is hidden by the way. It doesn't occur to you to look System/Library/CoreServices? Does it occur to you to look for ping.exe in c:\windows\SysWOW64\ ?
Why should any of this be linked? It's important to you so Google would often suffice. Look at a typical Windows 7 machine. There are 300 (exactly) applications in the SysWOW64 directory, the vast majority of them powerful, and the vast majority of them no one will ever have a need to execute.

It's an even more trivial matter to download a precompiled binary from wireshark.org, but, as another response already noted, one thing Wi-Fi Diagnostics provides is that you don't have to download and install it, much less compile it. It also offers a pane to get information about Wi-Fi networks your machine is seeing and a signal-and-noise graph, and to report that information to Apple for troubleshooting, and it can report various Wi-Fi network events.
In addition, if you're not the person who's going to be reading the capture, it offers a much simpler UI than Wireshark (which is intended for people who are going to be reading the capture).

For example, I frequently use Screen Sharing directly from this directory. If you know the host address and credentials, you don't need more than that.

SysWOW64. When a 64bit app accesses this folder, it still gets this folder. When a 32bit app accesses this folder, it gets this folder. Neither, however, should be accessing this folder - even though a 64bit app might have to interface with 32bit system files.
Which leaves the situation that a 32bit app needs to interface with the 64bit system files. On Vista/7 64bit, this can be done by accessing the hidden folder SysNative. On Windows XP 64bit, this can be done in the same way but only if a specific hotfix is installed (not installed by default nor pushed out by Windows Update), or by temporarily disabling the File System Redirect.
The confusion carries on through with the CSIDL and KNOWNFOLDERID names.
I haven't touched this stuff in a few years now, but I recall it being some backward compatibility issue. Presumably in Windows' own components that would be bypassing the file system redirection as otherwise the filesystem redirection should mean there is no backward compatibility issue.

That directory also houses applications that are not usually directly invoked by the user, but from another event (apps like Installer, Bluetooth Setup Assistant, Keyboard Setup Assistant, and so forth, most of which are started by taking action within the System Preferences app.)

Option-click on the Wi-Fi menu extra by Guy+Harris · 2011-09-08 08:04 · Score: 1

As the AppleInsider article says, you launch it by holding down the "option" key and clicking on the Wi-Fi "menu extra" and selecting the "Open Wi-Fi Diagnostics..." menu item. It's "hidden" because it's in an option-click menu, not because it's in /System/Library/CoreServices (it's in /System/Library/CoreServices because it's intended to be launched from the aforementioned menu).

In a number of cases, option+click will bring up a menu with more items than the menu you get by just clicking has. I'm not sure whether Apple document that anywhere, so I'm not sure whether that stuff is "hidden" in the sense of being something Apple doesn't tell you about at all or "hidden" in the sense that you don't get it by default.
