I don't normally post these in my LJ but .. my friend
prdct is having a friending frenzy
here.When I first saw these, I was like "WTF?" but I soon worked out they were just a simple way to make LJ friends. It invites anyone to click the link, read the author's entry then introduce themselves in the comments.
I think it's amazing how far these things can travel through the promoting of the entry via the author's friends, who then may promote it on their LJ in turn.
