First off, your blog was deleted as it wasn't really substantial for discussion. It was more meant for your userpage, and as such, you can find the information there now. Blogs should provide something substantial - you can read more here.
Secondly, you stated that you wrote the post for the purpose of getting a badge. You may not edit or otherwise post for that sole purpose - badge editing is a blockable offense as it encourages poor editing.
Technically, the contents of your blog was not removed - as I said, I placed it on your userpage, so your efforts were not in vain. With that being said, as I told you above, blogs need to provide more substantial discussion - you could perhaps come up with a more extensive theory and write your reasoning behind it.
Hi there, and welcome to our wiki. I hope you'll have a great time around here and become in a constructive member of our community. However, that also sort of why I'm leaving you this message: I wanted to impart on you the warning that this wiki does not condone badge-editing, the editing solely for the purpose to gaining badges. You can edit constructively and earn the badge that way, but please do not make meaningless and random edits for the sole purpose of getting a specific badge. Anyway, have fun around here and if you have any more questions, feel free to ask.
Okay. Thank you for telling me that. But I would like to know on what thing should I write a blog on? Can it be out-of-Avatar-world stuff?
And about editing anything solely for a badge, I think I won't do that. I thought that the blog presented my thoughts so I could do anything with them. I am not too much crazy for getting badges so as to edit something that is trivial and of no fair purpose. :)
