Well, that depends strongly on the person, doesn't it? :)
Apologies for sounding trollish, but I'm somewhat shocked at the reactions here. We have someone telling us that they work themselves into such a lonely place that the only thing keeping them sane is HN, and yet no one is suggesting he reorder his life and find a better balance so that he can find more enjoyment.
I don't think you're sounding trollish, but I do think you may not be treating this forum as a casual social setting in which people sometimes make statements to convey a feeling, rather than because they are literally true.
Edit: I forgot to say:
I also think that for a lot of people who hang out here, and to a lesser extent on proggit, etc, this online community really is one of the most fun, engaging things they have available to do. Conversation online with those who are interested in similar topics could easily trump conversation in person with those whose interests bore you. Even if we grant that being in the real world is an important attribute of "fun things to do", it's unlikely to be the most important.
