In the field of educational technology a creepy treehouse is an institutionally controlled technology/tool that emulates or mimics pre-existing technologies or tools that may already be in use by the learners, or by learners’ peer groups. Though such systems may be seen as innovative or problem-solving to the institution, they may repulse some users who see them as infringement on the sanctity of their peer groups, or as having the potential for institutional violations of their privacy, liberty, ownership, or creativity.

Twitter - like many emergent genres of social media - is structured around networks of people interacting with people they know or find interesting. Those who are truly performing to broad audiences (e.g., "celebs", corporations, news entities, and high-profile blogger types) are consciously crafting consumable content that doesn't require actually having an intimate engagement with the person to appreciate. Yet, the vast majority of Twitter users are there to maintain social relations, keep up with friends and acquaintances, follow high-profile users, and otherwise connect. It's all about shared intimacy that is of no value to a third-party ear who doesn't know the person babbling.
