How powerful actually is the Danish Gambit?

Although I will use the English Opening on my next game but Danish Gambit which takes me 3 months to master is still one of my favorite gambits.

Today I am going to show you from my opponent point of view what type of damage the danish gambit can do to him! I am playing the white pieces with the Danish Gambit opening and my opponent is playing the black pieces. He resigns after I have brought my queen down to assist the rook. I do agree with some of you that Danish Gambit is not effective against the player with 1800 and above but it is good enough to win against the player with the chess rating of 1700 and below.

The game board has been flipped so you can see from my opponent point of view and visualize that you are actually playing as the black king!
