I speak as someone who flies both powered A/C and gliders (ex instructor). This is how I try to do it. When descending IFR (with let's say a RIS and not in IMC) I will try to maintain a level above the Cu tops as long as practical. Someone previously said you sould pay a good look out when in flight and I truly agree, however not all the types of flying or A/C give you much time for that. Still I try my best but as begin to descend I begin to worry because I will certainly descend thru those nice fluffy Cu and there is no way anyone will be able to spot me. 170 Kts coming from above not a chance!!! I recently got reported 11 targets and only managed to see one, I guess very few gliders pilots saw me as well. It does require to be extra vigilant yet it doesn't seem to be much I can assure you. If we can try to understand how both worlds fly then that's another good way to prevent accident.
Just before I bore you with more, think about 2-3 years ago, a Airbus 320 collided with a G103 (or vice versa). Lucky escape because the glider and the Bus managed to land safely (not crash). It happened in France and I bet you it was a scary experience for all the pilots involved. to be fair this "see and be seen thread" applies at all level of aviation and it is only up to us keep it safe.
