I recently moved from playing exclusively at PokerStars to mostly at FT.
I hate shortstackers but play badly against them. At PS, I played 50bb min tables exclusively but several folks have mentioned how bad the 50NL and below SS players are so I decided I should check them out. In an effort to learn how decent SSers (skill wise -- not human being wise) think I decided to try and become one for a short while. 20k hands and -15 SSBI below EV later I just couldn't take it any more: I fired up just a few FTP deep tables and promptly made 1/2 BI (full stack) without running well. Of course starting new tables helped. God it feels so refreshing to have to think on the turn and even river!
I am going to continue shortstacking for a while longer to improve my SS game. I know other SS haters may despise me for it but I really can't motivate myself to learn SS ranges (in order to counter them) without SSing myself. The good news is that my endgame is to play full stack but have a better understanding of how to crush short stackers. Presumably some of this knowledge will still be valuable when FT raises the min buyin to 30bb.
RANDOM COMMENT: FT canned avatars suck. I like PS avatars which actually reflect something about the image the player wants to project but I have the idiotic FT avatars turned off.
