Greeting a person over the internet


So I was wondering, how do Japanese people greet each other when they are, for
example, writing on a blog or recording a video? My doubt comes from the fact
that their greetings will be directed towards someone who is unknown, and that
the greeting will be seen on a unpredictable time. Someone who accesses the
blog (or watches the video or whatever) could to that at anytime of the day.
Does that even matter? Or one should take into consideration the time when
they're are writing/recording? Or neither?




Greetings on the internet are largely the same as those that would be done on
the phone or in person.

> こんにちは with be fine for a friend etc.  
>  お疲れ様です would be fine for a work colleague  
>  はじめまして for someone you are meeting of the first time.  
>  うっす is even acceptable for very casual situations.
