REFLECTIONS

How it works: "StumbleUpon is a discovery engine (a form of web search engine) that finds and recommends web content to its users. Its features allow users to discover and rate Web pages, photos, and videos that are personalized to their tastes and interests using peer-sourcing and social-networking principles." (from Wikipedia)  (My highlighting )  I believe it expands  knowledge and understanding about a subject or situation. But does this limit me to my own personal situation and knowledge? Does it l imit the range and extent of my experience? I'm reluctant to use it because I don't want it to limit my ability to find brand new interests and information. It is good in that I get what I like. But does this prevent me from finding something I never knew about that I might really find interesting? It feels strange to be interacting with a non-human. I suppose that if I look elsewhere for something completely new I'll still be able to find it.
