Is there a social website or blog where I can find more music enthusiasts like me?

Hello there,
There a a great many guitar forums. I don't know anything about the flute, but I suspect there are flute forums also. Most guitar forums are based around either 1) the type of music or 2) the type of guitar. For instance, the are forums for Stratocaster players and forums for Les Paul players. If by type of music, you can find metal guitar forums or surf guitar forums. Most forums are a good resource for information about gear and playing. They are also a good way to interact with players of similar interests.

You should be able to find some forums by doing a Google search.

Talk to you later,
Norm
