You stalk him on Instagram,

The video likely resonated due to its relatable humor for a niche audience (programmers/tech enthusiasts) who understand the "stalking" culture on platforms like GitHub. The concise and witty on-screen text combined with the creator's expressions creates an engaging and shareable piece of content.

The creator humorously contrasts her method of "stalking" someone on GitHub with the more common practice of stalking on Instagram, implying a difference in their approach or interests. The video uses on-screen text to convey this message with the creator making subtle facial expressions.

GitHub: it ACTS as a platform where users can "stalk" others by viewing their profiles and activity. Removing it would change the context of the creator's statement. Instagram: it APPEARS as a platform for comparison. Removing it would not change the core action of the video.
