Are "virtual relationships" really valid, or are they just a novelty?

I got involved in Answer Bag in that gap between getting shit done during the day and before I went to bed.
Then, AB changed badly, and one of the people I sort of liked suggested that I should go to Fluther.
So, I did.
And now, when I have time between work, working out, my girlfriend (whom I love dearly) and the other duties of existence, I check in on Fluther.
It is clear to me that there are personalities on Fluther that I feel an affinity toward, even though I really do not know anything about them other than their questions and comments on the site.
For example, I think that I have a thing for @lucillelucillelucille, even though I figure she is married, and I have the perfect relationship with the love of my life.
I think I would like to go to a football game or go fishing with @cruiser
I think it would be fun to get drunk with @ETPro
I think it would be fun to get into a fight with @Zen, and I am pretty sure I would put him in the hospital.
But it is all bullshit, is it not?
Or is it?
