I spent a good 3 months of spare time building all the aspects of the website (front and back ends) from scratch. Besides the time I pay hosting/domain costs out of my pocket. Also I can't stand websites cluttered with adverts (thank you hubski, I hope you never succumb to the dark side of marketing : ). I want to keep Lucid Tree as clean as possible and not detract from the content with ads. I obviously didn't build the website to make money but wanted to have a way for people to show appreciation for my effort and running costs, if they so wished to. Also, it's a way of showing support for crypto-currency. I like the idea of open-source decentralized money generation, I think it has huge positive potential, especially in an age when the banking industry seems to be immune to the abuse of its power. Sorry for the ramble, I hope it answers your question.
