General ⇒ Using $\cdot$: important?

[latexforever]

Hello everybody,

I would simply know whether it is so important to use the $\cdot$ command between two factors to signify it is a product, or if the $.$ dot is also nice?

Thanks

I would either use $\cdot$ or nothing at all, never $.$

Totally agree
