I stopped participating in BOM when I learned it was mandatory to have a PA subscription to enter. I had a subscription to PA, but I sometimes found it had articles I wasn't interested in. So, I let my subscription expire and now I just purchase editions off the news stand when I see an article I want to read.
As it turns out, I rarely miss buying an edition. Also, I had a lot of trouble getting my subscription mags in the mail. Missed editions, no return of emails... I was frustrated. I found it easier and more convenient to buy it off the stand. So, I'm still supporting the mag, but I don't have a subscription. BOM has become BS in my opinion, and by the looks of it, other people think the same. You asked.
