A sign that you've been blogging too much: blog deja vu

Antonio Ganci says (blog in italian) sometimes when he's about to blog something, he gets this feeling that he already posted about that, kinda like blog deja vu, then he actually checks the old posts just to find out he hadn't written that post

I thought it was funny, hasn't happened to me yet, but probably happens to a lot of people; I find the Deja Vu effect quite interesting... and I few days ago I saw the Deja Vu movie which was pretty good (but I thought I found one error on the movie)
