[tor-relays] Increase of number of new relays and exit nodes

I am wondering with the increase of number of new relays and exit nodes how this might be affecting the other ( non- new ) relays and exits?

I have noticed over the past several months that the amount my exit relay was being used has drastically dropped as the new relays and new exits have come online. Is this normal to see my usage drop noticeably?

Is this going to be a continuing trend as new relays and exits join with what we already have, that some relays / exits will see a lower usage from their nodes?
