IMO

It's just easier to say it yourself before you have some jackass say IN YOUR OPINION DUUUUUR!!!1one
 
Well, that and it is nice to re-exemplify the fact that it is in fact your own opinion, and not just the opinion you got from your favorite artist saying it in an interview or something.

"Yeah, thats totally wrong cause like I read in an interview with Fenriz that he thinks its like wrong and like, he is in darkthrone, so like his opinion is right."

"Well, IMO, you're a fucking twat."
