It's probably all been said above, but I'll use a low-frequency wave for:

• Panning: Slow LFO into the pan CV-input on a mixer—it slowly pans the signal back and forth in the stereo-field.
• Volume: Plug an LFO into the level-input on a mixer to slowly fade the sound in and out.
• Sirens: Plug an LFO into the 1V/Oct (pitch) CV-input of an oscillator to make a police-siren.
• Switching: Plug an LFO into Plaits' model-input to jump from voice to voice.
• LFO: LFO another LFO.
• More: Buy an attenuverter with offset-control for more LFO-fun!

There are millions more uses for LFOs! Everyone always says you can never have enough VCAs, but I think you can never have enough LFOs.

Maybe. But many times better results will occur using fewer LFOs into more VCAs than the opposite. Adjusting the LFO on the way to the VCA, or using the VCA to do the adjusting. This way the LFO can still be 'evident' in many areas of the patch, without being necessarily recognizable. The classic example is the single LFO of many vintage polysynths. While there's a strong case for having at least two LFOs, having more routes and destinations for the single LFO is more important -and patch economical- than having many LFOs.

A few LFOs into many VCAs is greater than Many LFOs into equal or many VCAs.

This tends to hold true despite one's preferred style of output. It's less about genre than it is about human perception and expectations.
Treat utility modules as stars instead of backup singers.
Treat power supplies like Rockstars instead of roadies!
Chase magic sound, not magic parts.

Just think of it as a cyclic pattern of modulation being sent to whatever destination you choose. Rather than a "one shot" enveloped shaped coming from an envelope generator which (generally) only happens when it receives a trigger. THE O in LFO stands for Oscillator so that's basically exactly all it is. Not much more. It never stops oscillating, just like a VCO

for dubstep wobbles ...this is what LFOs were made for, every other use is stupid.

This be the true true. Imo it's the key to cohesive patches.

Also - Wavetables are for dubsteo wobbles also - all other uses are even stupider.

On actual suggestions regarding LFOs
you can ram a bunch of free cycling LFOs into a min-max module and get random-esque modulation source.
