Steven,
thank you for the reply..

From it I gather that in the interaction between mass and gravitational wave, no energy is absorbed (unlike in case of EM waves)?

I would expect something like tidal effects due to gravitational field gradients that propagate through space/time.
Was that way of thinking in the core of Weber's idea (GW prompting the metal cilinder to vibrate at mechanical resonant frequency and picking those vibrations with piesoelectric sensors)?

Gravitational waves act like a mass spring damper system where the amplitude and energy decay over time.
By the time GW150914 reached us only a minute amount of the original energy and amplitude remained.

Not sure of the effects of a gravitational wave originating from the distance of the LMC but nearby you would be flattened in one direction and streched out in the perpendicular direction.
