Thanks :) Yup, I source news from local news portals as shown in the website. Hourly, each source is crawled in each relevant category to get the latest news items, and stored into a database. Another job then goes and fetches the body of all these articles. (I use https://github.com/robfig/cron for cron jobs). Server and HTML templates are both Golang. As for the aggregation (grouping) algorithm, I'll just say that it's straight out of the textbook http://infolab.stanford.edu/~ullman/mmds/ch3.pdf
