Yes they are dying (except for the biggest one) and I had fun being a kind of big part in the faucet world back in the day. I gave away about 20 bitcoin to total strangers on my many websites over the years. I even had a part in the creation of faucethub because the owner read an ebook I wrote about how to run your own faucet website, he then went on to create faucethub. 

I never "made it rich" but I had a blast being part of history.
