I'd like to share the favorite things I wrote in a year of professional web scraping blogging at ScrapFly and my key takeaways.

Asynchronous programming can speed up web scrapers astronomically and is by far the most important scaling step when dealing with big projects. What exactly is it, how does it work, and what are the best ways to take advantage of it?
