If not for the fact that I am terrible at keeping in touch with friends and family, I would delete my Facebook account. I have always preferred Livejournal for social networking. The "blogging" nature of this site requires more thought and effort to communicate with others. With Facebook, I feel lazy and am far too easy to find. I have a hundred "friends" I could do without, but don't have the heart to exclude them from my "friendship."
That's part of the reason I have resumed writing here... I like being somewhat anonymous, but still "social." And, I miss writing - which I have not done in years.
I miss the old days of Livejournal. Aside from a few regulars, it seems to be a bit of a ghost community.
