Can someone explain feeding FR24? Aircraft have transponders, except small planes and the military. 

Keen to know more.

I had to first enable Flight Crew, then searched for Geekzone.

I'm well.. obvious ;)

Try this: FR24 - How it works.

Even aircraft that don't have ADSB can still show up if you have enough receivers nearby - they can location the position of the aircraft based on knowing exactly where the receivers are, and exactly when the transmission arrived.

I do think FR24 is great.

We're across town from the airport (Chch), my wife flies back in tonight - check FR24 and her flight was 25 mins late (departure), but at present progress making up a bit of time - get an accurate ETA of landing, she's only got hand baggage (my credit card hopes), can time pick up so I don't need to find a park. If I used google maps, pretty sure I could time the trip across town very accurately too.

Related topic kind of, bored on flight last night (A320) my phone GPS works fine when in window seat - got fixes on 20 satellites.  Using GPS apps (GPS essentials and a marine GPS app) could display SOG, altitude with reasonable accuracy, vertical climb, but also cabin pressure in hPa but also converted to altitude equivalent (about = 7700 ft when at cruise at 38,000ft), and plot the position on a background map. If the pilot got lost - I'd have known <g>. Actually kind of nice on a clear night - can be hard to pick up what landmarks/lights are.
