I'm sure you are touching lots of stuff.  
I'm having some weird issues.  

I tried quoting a post where you said you were testing stuff, and it said "I can't just modify any post."
Then I tried to back up and try quoting and rewriting the post, this time it said that the post was already made.  
Also I tried tweets, and it worked but then I went back, and it stopped working and said Error Invalid ID and stuff.
