🌐 Introduction to Reddit and Extractor Package

The speaker, Marcin Grass, introduces the viewers to the website Reddit and emphasizes its awesome features. He proceeds to demonstrate how to use a package called 'extractor' to extract comments from Reddit posts and find URLs with specific terms. The practical lesson involves selecting a subreddit at random and showcasing the process of extracting comments programmatically. Marcin also explains the necessity of installing the 'tidyverse' and 'reddit extractor' packages for the demonstration, and guides the viewers on how to do so.

πŸ” Searching and Analyzing Reddit Content

In this section, Marcin discusses the functionality of the 'reddit content' function from the 'reddit extractor' package. He illustrates how to extract comments from a chosen subreddit by simply pasting the URL into the function. The output provides details such as the subreddit name, comment date, and comment structure. Marcin then shows how to write the extracted comments to a CSV file, suggesting potential uses like text-to-speech synthesis and monetization on platforms like YouTube. He also touches on the possibility of stripping or utilizing markdown language captured in the comments.

🎯 Targeting Specific Comments and URLs

Marcin introduces the 'reddit URLs' function, which allows users to search for URLs based on specific parameters, such as search terms and comment thresholds. He demonstrates how to search for URLs containing the term 'Trump' and filters results to only include URLs with at least 20 comments. Despite a minor confusion with observation numbers, Marcin successfully extracts the URL with the maximum number of comments and reiterates the potential of using such data for various purposes. He also cautions about the limitations of data extraction to prevent overloading the system.
