Is slow playing AA really so common in NL???

[Webster]

I'm making the transition from a $5/10 Limit player then to NL SNGs and now working into micro NL Cash games.

In my first serious 600 hands I have run into SO many people slow playing AA. Is there something I'm miss here? I've beaten them a few times and have been crushed more then once.

In Limit slow playing was a no no. Have the rules changed of am I just running into micro players playing tricky.
