Full Tilt - knockout mtt's help

[sooooooted]

Just entered one of these to see what it is all about and I soon got the picture, people are going all in/calling with basically nothing just to try and take each other out and win 1/5th of their buy in back.

Anyone have any tips on how to play these, Just got past the first hour and I have been playing really tight so far, upto about 3.2k and took 2 shortstacks out.

Seems like a lotto to me.
