Reddit is so big, it's difficult to make a general comment about it. There are so many strong communities on Reddit, and because it's a bit difficult to find your way at first, you definitely get a sense of belonging once you "get it".
When you're not searching for something, it's always a good place to stumble upon interesting content.
It's a great resource if you're looking for something specific, although the internal search isn't as good as using google and appending "reddit" to your query.
