this will be an every day thing

What do you mean? Can you define inthoseastic? I'm afraid I don't know what that means.

I think you might want to go more in depth and not just say she's enthusiastic (the correct spelling) also blog, Rainbow dash and isnt she very... (No a) finally to correct the title. Sorry my grammar nazi just took over)

I don't mean to hurt you, but I hope this isn't an everyday thing if the grammar is this bad. Please further your efforts in making sure each post is legible. I didn't think you even meant "enthusiastic". I really thought "inthoseastic" was a whole 'nother word I didn't even know.
So, let's rewrite this sentence.
Hi! I'm Fluttershy88 and this is my new blog. Today's topic is Rainbow Dash. Isn't she enthusiastic?

Needless to say, we would like examples of her enthusiasm and if you are feeling "inthoseastic" yourself, you could even take a look into her psyche.

I'm going to call you Intho now.
