well, it seems to me you don't visit the live commentary thread much.
i kind of agree with the main idea but some demented fans of this sport who don't always have access to watch a match on TV or on a live internet stream (most often because the match isn't televised in the first place) resort to read comments about the match online. It's boring but it's all we've got sometimes, and it gets interesting when you have a bet in the match. Yeah, i've been there too.
I guess those are the people walking down the street without looking up. The ones whose iPhones I try to knock out of their hands with my elbow.
If I am not watching on a large screen HD TV, I only need to see the result later. I don't want to know that Gasquet hit another great backhand, within 5 seconds of his scoring the point.
And I don't bet. I preferred to be able to retire early, rather than subsidise the early retirement of some bookie.
