Thanks! These are just core features we have launched. We will continue building more useful features, like lists, reviews, concerts etc. around your follows.

Entora is built using Python/Django, PostgreSQL database and ElasticSearch for search and cache layer.

For static files: Amazon storage and Cloudflare as an image proxy. Linode hosting (8x instances).

The biggest challenge is merging data from different open source databases and validating that musician John Smith is same person as actor or writer named John Smith from totally different data source.
