You can comment instantly but if you are going to self upvote while you have @dustsweeper active you might want to self upvote at 30 minutes or later if you really want to try and get .001 steem power extra on every comment. lol It may or may not work though. Hard to say. I'm an expert I think but this site is complicated and the @dustsweeper vote is low and your Steem Power is low. You can watch you creation rewards to try and decipher stuff.
