Decentralised marketing seems to work pretty well. i.e. do what you want to do, use your current networks!

Twitter is a vibrant place for Bitcoin discussion & congregation. Bitcoin podcasts (e.g. What Bitcoin Did, TFTC, Stephan Livera) are good to see what's going on in the wider world.

I came to Stacker News because I'm interested in lnurl-auth and it's listed in the examples section: https://github.com/fiatjaf/awesome-lnurl

I think lnurl-auth, lnurl-pay & lnurl-withdrawal is well implemented on here and it is a good example for anyone wanting to try out a Bitcoin Lighning wallet.
