I absolutely love what Louis Armstrong had to say above.
In business, though it's good to know what other businesses like yours are doing, if you spend too much time thinking about other businesses similar to yours, you are not spending enough time thinking about and developing your own business.
The tone of this forum and the "beyond", as well as the high-quality and diversity of conversation, are the selling points. And people will join once they know a) this forum exists, and b) it's not all about slamming other forums.
