I tend to think of the people who were made uncomfortable by my antics instead, but I feel a similar sense of relief to be free of them. I've often found comfort in the H.G.Wells short story "The Country of the Blind".
I can't comment on what those sites do, as I've never heard of any of them. However it must be hard to get ahead of the herd when you are following it with technology like LAMP. I developed mod_libpq specifically to explore new technological pastures and it seems to be working very well. e.g. tracktype.org
It takes an extraordinary amount of drive to keep trying in the situation described, but where does that drive come from?
Do you have a vision of something that "needs" to be done and you just have to find out how to do it? ... Or are you driven by a need to do something, anything, but you still don't know what?
At some point these combined forces overwhelm you, you must risk everything and there will be no going back. Nor does success, however you measure it, bring relief because the goal posts keep moving.
