Those of you who have niche specific websites and directories, how often do you try to switch things up when it comes to the niches you promote or do you?

I know for me over the past few weeks ive been trying to change the staple of niches that i work with on a regular basis, trying out some new fetish based niches and content but at the same time, im also finding it very hard to try working on these newer niche concepts because im so used to cranking out sites and galleries based on existing content/sponsors that i know sells.

I guess im finding it hard shifting some of my focus away from the sites, products and sponsors that i *KNOW* sell compared to putting some of my time on sites, products and sponsors that im not really sure will sell, even though they might be the next profitable niche for me.

How often do you folks try out new niches and if you do, how do you find your attitude towards building sites for new niches, compared to building sites for niches you know will generate income?
