Great questions. 

Think of nostrlogin more of a trampoline to nostr for devs with apps already built on a traditional web database, with traditonal log in options (google, email, twitter, github).

Probably it would make sense to add a sales pitch of reach 10,000 nostriches who are ready to use your product/service to the website. 

https://www.plebwork.com/ is the site I had in mind. The founder is open to snd curious about considering nostr. 

I’ll continue to add feedback as I receive from the founder.
