As per popular usage and understanding, an 'Otaku' is a person who has an obsession with Anime/Manga. Now, while I may not be obsessed about either, I certainly have more than a passing interest in it. So yes, I do like to think of myself as an Otaku because like any other Otaku I invest myself emotionally and sometimes spiritually into an anime and/or manga.
Again, compared to many other members on the site, I may have not quite seen as many anime or read as many mangas in my lifetime but rest assured, those that I have seen and read are both popular and intelligent.
When it comes to anime, I am a very visual person. I judge the quality of the show mostly by the quality of the animation. In recent years, especially Studio Bones, Ufotable and Madhouse have really set the bar high for it and I've never been happier. I primarily enjoy Action/Hack n Slash anime. My anime list on here will give you a good picture as to my tastes.
I've taken to reading Mangas fairly recently. The ones that got me started were One piece and Naruto. I am currently keeping my Manga reading restricted to a few titles as I would possibly overload my brain with information from both anime shows and manga.
I have come on here after much contemplation and procrastination for two reasons:
1. To keep myself updated as to the activities in the anime/manga world
2. To hopefully make friends with similar interests in not just anime/manga but also in life.
Well then, if there is anything else you wish to know then you must ask. I cannot guarantee an answer, but rest assured, I'll be happy that you asked. :-)
