This post has sat in my mind for a week now and it's because nostr:nprofile1qqspw5udc2nzw6wsj3plrrphe0343744h0ucz9e4g248chl3w8kh03qppamhxue69uhkumewwd68ytnrwgqs6amnwvaz7tmwdaejumr0dsq3gamnwvaz7tmjv4kxz7fwv3sk6atn9e5k7m7dh6a is right. NostrCal will need a reliable free option for public and private events to showcase how nostr can be better. I'm going to buy a new SSD today and use some hardware I picked up from nostr:nprofile1qqsplqcdmp63xzcnf7ln7faxnmkdscf6fxt53fcmtgn35uvlawhpfmgpzpmhxue69uhkummnw3ezuamfdejszrthwden5te0dehhxtnvdakqz9nhwden5te0wfjkccte9ec8y6tdv9kzumn9wspyfxrn last year to deploy a new version of relay.nostrcal.com that won't have a charge for using it. I'd certainly recommend looking at some paid plans from someone like nostr.land if you want long term private event storage but this will at least ensure users have a better first touch when exploring the app for the first time.

For nostr.land, I am working on a program to allow FOSS projects to gey their own
Also:
if it's free it will be spammed, if it's not free no one will use
