Final answer:
Yes, online forums and instant messaging are indeed examples of social networking technologies, as they facilitate communication and interaction among users.
Step-by-step explanation:
The statement that online forums and instant messaging are two examples of social networking technologies is true. Online forums are platforms where individuals can post messages and engage in discussions on various topics, which is a form of social networking since it allows people to connect and communicate with one another around shared interests.
Similarly, instant messaging services enable users to quickly exchange messages one-on-one or in groups, often in real-time, which is also a form of social interaction made possible through technology. Social networking technologies have a significant impact on the way we communicate and interact with each other, both positively and negatively, as observed with the phenomena of LinkedIn, and other major platforms.
