The web is an amazing outlet for people to feel like they belong to some kind of social group when they are otherwise introverted to the point of handicap. I can appreciate that this is theraputic to a point. I don't know that anyone claims celebrity due to a blog being published, but I'd wonder how much traffic someone's blog has to acheive before the publisher inevitably feels a sense of accomplishment (celebrity). You could say the same thing about people who post things on this forum or youtube or whatever. I can't explain exactly why I do it. I guess I get off on putting out some information with the hopes that it benefits a few people (sure that's in the context of a hobby but for some blogs it might just be a hope of entertaining someone). I also make short updates to my personal website just for the benefit of family members who like to hear what I'm up to but I'd rather not call on a weekly basis.
