I like hearing about the music everyone's playing - I always listen to the pieces and it's nice to get the variety. Also nice to see Raider's new guitar. (I must NOT buy a guitar. I can't even play guitar. They look so nice though.)
Fluke, to answer your question from ages ago (sorry for delay - Easter holidays) - I don't play in any groups at the moment. I know what you mean about playing at home alone. It is hard for me to maintain enthusiasm for playing from sheet music on my own on an instrument like the flute...just one melodic line (I need harmony!) and it just feels like practice rather than playing and enjoying the music. I think that's one of the reasons why I stopped playing flute for 20 years.
Also, after being in lots of friendly music groups at school I found all the ones I tried to join afterwards too serious. And because I was unable to play by ear and didn't understand how music was constructed, 'jamming' in jazz/pop/folk styles (which might have been more relaxed) wasn't an option either.
Now I play flute loads at home but the big difference is that I'm exclusively playing by ear, improvising and playing along to backing CDs (eg the Jamey Aebersold ones). This makes a massive difference to me and makes me feel like even on my own there's harmony going on and and I'm making my own music. It feels really different (and for me, better).
I'm hoping to join a group at some point but I think it would be a style that would reflect what I'm doing at home, so likely not classical (much as I enjoy classical music).
