It is a social interaction and it has effects of one albeit weak.

You can have bits of social satisfaction from hearing 'hello, how are you' from a store clerk or from watching people interact on TV. Definitely you can get it from getting responses to you anonymous or curated speach on the internet. Of course its not the same thing as honest interaction with your friend or loved one but it doesn't mean it does nothing for you.

Social circuits in the brain are so low level they can be activated by most superficial stimuli.
