Couldn't you get the same information through email or picking up the phone?
Sure. But that requires a separate activity for each person, and you have to remember to do so.
If you followed a number of technical blogs, you'd probably want to look into an RSS aggregator - to put all the stuff you want to get at in one place, right? Same idea here - all that information is in one place, where you can look most of it over in one fell swoop.
Isn't that a far more substantive form of contact?
A large part of the time, people don't want more substantive contact, for a number of reasons - some of them even good reasons.
And if you don't get along with people...why do you care when they get married?
I don't know about Majoru, but family obligations abide for many, even if they aren't terribly fond of said family.
