Other than Oh-My-God-What-A-Creative-Mind there's one more thing that makes them so much more enchanting than others. It's the pictures. The pics people put to enhance the effect, a particular thought has on the readers. Sounds convincing to me. That's why to make boring lectures and presentations bearable, they used powerpoint to keep the audience focused. Thanks fellow bloggers, that was really an eye opener for me :D. I took it to the next level. You would agree that moving pictures leave a greater impression on the reader
I love doing signatures and putting names on animated images :D.
