I've found myself posting less often than I used to, in large part because I don't want to post pointless drivel. This is my journal, and I want it to reflect me. Describing a few meaningless things I did is a waste of my time, and a waste of time for anyone reading it.
I think one of the reasons we see this so much, is that LiveJournal can be so multi-purpose. Traditionally, journals or diaries are a way to record your thoughts or opinions, a personal accounting of your life. LiveJournal, however, extends that into a multi-user communication forum. No longer is the primary focus for many people communication with themselves, but sharing with the community. It becomes less of a personal exploration or history, and more of an entertainment medium.
When done properly, this can be a great thing. You "meet" and get to know new and interesting people, are offered and provide some level of (virtual) support, and you can received opinions and thoughts of others through the process.
I see more and more entries, however, that are what I think of "telephone entries". They contain the same small talk chatty nothingness that occurs when two people aren't willing, or able, to make the effort to talk about something "real". Occasionally done, this isn't a bad thing. It's exhausting to discussing meaningful and through provoking topics all the time, but now we're seeing full journals of nothing but "I woke up, I'm tired, work sucks, boyfriend/girlfriend isn't treating me perfectly, got home, going to bed".
I guess this just seems to be a waste of time to me. Of course, I've also made posts like this myself. So it goes.
Updated: Bleh, this sucks. I had a really nice addendum here, and when I tried to post it, the LJ client harfed, couldn't connect to server, and closed the freakin' window. So, I just lost the update.
In short. . . oh, screw it. If you're interested in what I have to say on this, check my next entry. I'm just gonna write it there.
