I just have a low risk tolerance so instead of investing money back into my sites I put it somewhere else to earn a more predictable rate of return and to try to develop a different income stream not dependent on search rankings.
I have had too many sites lose their rankings overnight with one algo change to want to invest much money into any one of them. To spread the risk I invest offline, and online I have multiple sites. Usually with every big algorithm change if some sites get less traffic others might get more and my income tends to even out over time. I will never have a super star site this way because my time is split among sites and I rarely pay anyone to help.
I have been lazy for years, not adding much new content and not updating the sites. Now that is catching up with me. I have a lot of retrofitting for Panda, Penguin and mobile to do this year.
