... widgets ... what's the point of them?
The weather widget doesn't do anything...
How would FTM's Dashboard widget be more advantageous than my using the bookmark already in my browser?
The use of Dashboard widgets really depends on your preference and needs. Several utilities are exclusively available as widget, and if you need any of those you might gravitate to the Dashboard. Other widgets are just handy or fun. Personally, I rarely use the Dashboard except for the odd item that's easiest taken care of there because of an exclusive widget.
Your comment about a contrary weather widget sounds like it (or its internet source or connection) might be florfed. FWIW, this
Air Quality Health Index widget works for me. The availability of the FineTunedMac widget is simply a service to the Dashboard mavens among us. It's just one more option, that's all.
