Hook: Start with a bold statement about WhatsApp's global dominance (e.g., "With over 2 billion users worldwide, WhatsApp is not just an app; it's a global communication utility.").
Thesis Statement: State the blog's purpose—to delve deep into the core and advanced features that make WhatsApp indispensable for personal, group, and even business communication.

Section 1: The Foundation - Essential Messaging & Media (Approx. 250-300 Words)
This section is the core functionality. To reach 1500 words, you'll need to elaborate heavily on each point.

Use Cases: News updates, celebrity announcements, or local government alerts.
Section 3: The Fortress of Privacy and Security (Approx. 400-450 Words)
This is a critical area for expansion to meet the word count, as security is a major selling point.
