Ask HN: which are the best data science company pages or blogs that you know of?

With all the hype and buzzwords going around, great work in data science around simple but important aspects such as data cleaning, data visualization, data engineering etc. can get lost. Blogs and open source contributions are a time-tested way to get word out about your work. For example, companies like Airbnb and Google put out great content and open source software regularly. What are the other ways in which smaller organizations and startups have leveraged the web to get word out about their work, specifically in the data science domain? It could be in the form of team stories, interactive web-pages, etc.
