If the diary is fundamentally about loneliness, is the blog all about changing that? Reaching out from loneliness and solitude in the hope of finding like-minded individulas who share a common interest or have a mutual understanding of one another?
One keeps a diary for several possible reasons, including:
1) The inability to converse in the topics one details within it.
3) The lack of relationships or known people with whom one could offload.
Conversely, then, blogs, surely must be about:
1) The desire to exchange ideas and offer thoughts profusely.
2) The overt exposure of one's soul, moreover, to be an open book.
3) The seeking out of other people with whom one might find the ability to discuss ones personal life at length, without fear of being judged, or without being judged by anyone who matters.
Furthermore, after reading several blogs that I've stumbled across and some thoughts that I've scattered throughout my own, anonymity plays a very large part in the blogging culture.
I, for one, stuff my blog with personal thoughts, if you'll excuse the pun, with gay abandon. I'd include more if I thought no-one I knew read it. I'd include no personal information at all, and perhaps even give this up, if I thought my family had a handle on what I was up to here.
So, it seems, in blogs, as in in diaries, it remains: that sense of loneliness and isolation, dear reader. Blogging has the air of the confessional, though we're still careful about to whom we confess.
