A huge drag on my site load time is the AdThis and Facebook Like buttons
I find both are terrible for slowing down page loads. Also, any Twitter widget.
AddThis is the worst of the three, and disabling it is on my to-do list. Facebook is bad, too, but I get far more benefit from that, so I'll tough it out for a little longer.
