I might make a personal twitter account with pokemon stuff now haha! Sounds like fun!
Manga is written with pictures... anime is usually derived from a manga. However, the pokemon anime is different from the manga because the manga is about Red and the anime is about Ash.
I just dont use it much. I had to make one for spanish class because she wanted us to tweet at her in spanish haha. I found it kind of confusing and I dislike the character limit.
