Hehe!!! True!!!! 
I don't know about the general trend, but as for me, I maintain a perfect balance between my family, my social circle, relationship, blogging, studies and work. Never have even been tempted to be a "nerd". I admit to being a bookworm, but that doesn't mean I lack social skills, it just means that I love books to the extent that if you soil a single page I chop ur hands off! (so beware!
)
I don't think blogging means you lack social skills, it's an easy platform to express yourself and be heard. I agree with what Anurag said.. Of course there might be the few introverts in the blogging community but that isn't something demeaning.. It just means you are different and have a different way of expressing yourself. I hate the term nerds btw.. It sounds like a derogatory word..
