Better late than never indeed. I'm back and never got it done but I'm still interested. Were you one of the ones who messaged me through plebwork? If not, let me just say the purpose is to provide a second data point to what nostr.band has provided. I'd like to get someone (maybe you) to develop it and then host for a year. The format should be a daily and weekly graphs with all npubs and then a lightly filtered version. If it goes well, perhaps we can build more into it.
