Before I came here I had visited several Zen online boards (in different languages), and I was very disappointed that there was no difference to other online boards. (I had been moderator in an online forum years ago and it was just crazy, you wouldn't believe it). Lots of people seeking attention, even people who seemed fond of arguing. And the one thing I had expected least from Zen folks: lots of attachments - my school is better, that sect just doesn't get it, you must reach, reach, reach enlightenment, oh nooo he just said the forbidden "E" word! I felt almost appalled.
I kind of accepted I would carry on practising on my own when I stumbled upon Treeleaf. And it was the place I knew I would feel comfortable with. It is like an internet Zen oasis.
Still, I agree with Chet that we should check/review our own practice from time to time. I personally don't want to be attached to it. As soon as I feel I can't live without it any more, then I know something is probably wrong.
