Its hard to be that guy but yes always betting at 2 seconds gives you the edge of not having a timing tell. Plus if you put your opponents on crazy tilt like stated above you have a huge edge. I used to do this a lot. Not a terrible strategy. Not to mention if you tend to act to fast or have bet regret this will allow you to clearly think through all the possibilities and ranges of your opponent and make an informed decision vs having a play in your head before your opponent even bets.
