It's a giant cluster fuck of annoying explanations!

Slacker Seat Tube Angle I.E 69 Degrees, puts the Bottom Bracket Closer to the Front Wheel thus making the Bike Ride like a shorter Frame BUT! It also puts the Seat Backwards, Thus making the Top Tube feel a little longer! That's why You see A LOT of SUPER Tech Frames like the Benny L using 69 Degree Seat Tube Angles.

Steeper Seat Tube Angles, put the Seat Closer to the Head Tube, Making the Top Tube Feel Shorter. Great for Flatland Frames & it pushes the Bottom Bracket Backwards, making the Wheel Base feel slightly longer.

My experiences are that 69 Degree Seat Tube Angles are great for Street, You can have a 21.25" Frame that feels similar to say a 21.5" Frame but will Spin more like a 21" Frame.
