Nope, I'm out. Funnily enough I let my first domain drop just last weekend and started 301'ing domains I will be selling or dropping to the few site's I'm going to keep. The sites I'm keeping have communities I feel responsible for so I will just leave them on cheap shared hosting because my conscience won't let me abandon them. 54 domains from what was once a thriving network I had hopes of being able to live off but I lost hope of that long ago.
I'm sure that many domains sounds like a spammer but that is't true. I just kept trying new niches and my hat was so white it sparkled. Sadly, unjustly, I think my biggest problem was trying to do the right thing and follow googles guidelines too closely. What a fool.
I've been contemplating it for a long time now but I can no longer justify the god knows how many hours per year I put into it. Making websites has been a life long passion but the constant smackdowns are too demoralizing and it was starting to affect my emotional well being, so the decision has literally torn me apart :(
