No not really. Pretty typical growth last month.

I use twitter like nostr clients (damus, snort) daily at this point. 

Aggregators are designed for signal intently. Twitter-like apps are a more whole cloth experience - and can provide signal finding too if they want.

Has SN been less active since damus blew up?

SN and nostr are two different things.
Not complementary, not opposite, not competing.

nostr is for sending memes and a message to the whole world. Notes. Not chats.
SN is to have serious discussions and read news.

Much greater signal on SN then Nostr IMO

As I said: two different things.
