95% of the golf I play is solo, not because I'm an antisocial git, but because I try to play so much. I couldn't possibly organise that many games - particularly at the time I tend to play. As others have said, early or late tends to help this, but it just depends on where you play, I think.

That said, I always enjoy joining in with others when I can, but it can be nice to have a mix of the two.
